Hi @Steve-Mcl , Node-Red Team

Gentle prod - would you know if the FR for changes to Link Call node per below is planned to be picked up for 3.1 ?

[FR - Fixed Target Link Call - 2 new FR requests](https://discourse.nodered.org/t/fr-fixed-target-link-call-2-new-fr-requests/66905)

Thanks in advance.

It depends if someone wants to contribute to help make things happen. The backlog is huge and ultimately things depend on who turns up to do the work. I have my own set of priorities I'm working on already.

Thank You Nick. I will check if someone from our side can help on the specific asks. Not sure at this stage.  
Would you be able to already indicate **tentatively** - which items you foresee making it to 3.1 ?

My Bad.

Instead of

[FR - Fixed Target Link Call - 2 new FR requests](https://discourse.nodered.org/t/fr-fixed-target-link-call-2-new-fr-requests/66905)

it should have been :  
The below is the one i am interested in. I will also if someone at my end knows and can pick it.

[FR : Dynamic Link node enhancement request](https://discourse.nodered.org/t/fr-dynamic-link-node-enhancement-request/65179)

Main piece being instead of "target" have typedinput to allow any string / msg attribute etc. to have dynamic link name.

My mistake on the typo on the links.

Hi @Steve-Mcl,

Would you be able to assist ? Mainly wanting to know if foresee you would be able to pick this up anytime soon ?

While i am checking if we have anyone who can pick this up. I have a strong feeling we may get stuck in red-tape.

I will pick this up. I think it has merit. But you must promise to beta test 😉

I have updated the Feature Request issue with some designs

Users are welcome to review and comment on the design options offered.

> <https://github.com/node-red/node-red/issues/3836>
>
> \_This FR should be considered a backlog item\_
> 
> Requested several times are var…ious enhancements to the Link Call node... 
> 
> 
> 
> 1. Timeout error to be optional
> 2. Default (fall back) target if \`msg.target\` not found (like the \`default:\` in a JS \`switch\` statement)
> 3. Pass through if target not found
> 4. make target a typeInput to reduce need for change nodes before each call
>  
> \### Item 1
> The reasoning behind this request is sometimes the user may elect to NOT call the link-out-reply (e.g. filter replies) based on a certain criteria but in doing so an error occurs.
> One option here could be to use \`0\` to mean no timeout.
> 
> \### Item 2 + 3
> These feature would be additional capabilities and would override the current behaviour. 
> An example of the requirement of item 2: if target "add10" is not found, a default link could be called for alternative processing. 
> An example of the requirement of item 3: if target "add10" is not found, the \`msg\` should pass through and be routed somewhere else based on the fact it was not processed. 
> These 2 features could be added in the form of a dropdown option "Missing Target"...
> \* Raise error if target not found (same as original)
> \* Send to fall back target if target not found
> \* Pass through if target not found
> 
> My addition to this would be to add an \`error\` object to any \`msg\` that was passed through or was sent to the "fall back" link target so that users can determine what happened to the msg.
> 
> \### Item 4
> A typedInput, defaulted to \`msg.target\` that permits the user to specify where in the \`msg\` the target has been provided.
