Hi hyperion, I do not think this is currently possible.
We have to remember that an MFC preset is just like a "superset" of the Axe-Fx preset, i.e. it includes the Axe-Fx preset as a base but also many other things (e.g programming of other MIDI devices, internal IA, external switches, etc.).
For this reason I think an (acceptable) compromise would be, just give the feedback of the Axe-Fx preset, show the IA switches status and switch off the LED of the active preset LED (just to show there is no MFC preset active).
I suppose this is feasible, but in case this will be included as a possible enhancement we have always to remember it is a compromise as we switch from a full MFC preset to a pure Axe-Fx preset. May be that for you, and also for me, what I've imagined before is enough, but there'll be surely somebody that will want something for external switches ("I want a default for them as they switch my Mark V channel using my..." :? ) or many other esoteric usages I do not image ("Is it possible to set the expression pedal to their min value to stop my rotating speakers ? (David, UK)" :lol: ).
These are the reasons why I suppose the feature you would like is (for me) linked to the support of all the 384 presets on the MFC (it would make it all easier, switch a preset on the Axe-Fx, the same preset will be acted on the MFC (with all its settings)).
