Changing Group Name using Subflow Env Variable

Dashboard
1

I've been using node-red for a couple of days and are still learning.

I have a subflow that contains several gauges that are used on multiple different inputs, and are trying to set the Group Name using an environment variable that is passed to the subflow from the main flow:

${location}

However this does not appear to work.

Is this possible and if so how ??

Many Thanks
