Question: Has anyone come up with a work around for instant adventures changing group arrangements when using FTL?

I am using Lax's FTL setup. The issue is when I join an instant adventure it rearranges the party layout. So the F1 through F4 keys are no longer targeting the right characters.

I was thinking of making "targetexact" macros keybound to F1 through F4. Hoping that will work with FTL. If you have a better solution, I would love to hear it.
