Options in subflow to have a dropdown list of options

You can set things to be constraints in the subflow.

I have a setting that has multiple options, so boolean doesn't quite cut it.

So is there a way to make a drop down where that option is?

eg:

So when you open that drop down you only see the 4 options.

Is that possible?

Yes.

Thanks Steve... I am still fumbling my way around subflows.
