Is there a way to modify a Rig through the Rig Manager?

Currently can only be done on the Kemper.

I'm hoping for this too. Currently I miss a good work flow for bulk editing my original rigs (adding my favorite pedal chain etc.)

I've always felt that something in the way of relief will come our way in this regard; I think it's just a matter of time.

Cabinets, FX, and who knows what else could be handled by RM at some point or by an editor that communicates with the app.
