Expander control in Midi

[skybox]

I have midi controlled synths going into my rig to be modulated by external effects and in order to trigger expander envelopes it would require me to use a channel that I currently do not have availability for.  Would it be possible that when the expander is connected/detected that we could control them in the FX column? A case use would be to use the envelopes with MIDI on the same track.
