Is it possible to create a dropdown selection for Subflow's Environment Variables?

Click the right angle expand button left of the word "name". More options inside.

@Steve-Mcl is it possible to have a different set of options depending on the selection of another environment variable dropdown list?

I don't think so. You might be getting into custom node territory there.

@Steve-Mcl Figured it won't.

It also won't allow me to select flow or global for input?
