+1 again so I guess its +2 for me lol.
But I can see how switching out DynaCabs could be an issue. If I remember correctly, all/most factory presets have Dynacabs in Channel A. So if the DCab slot is replaced with, say, an Ampeg 8 x 10, the factory preset that uses that DCab slot, it will be the Ampeg Cab even though its supposed to be a Fender Twin 2 x 10 lol. Or the cab slot would be empty.
Also, I'd imagine that if re-adding the original DCab, would mic placement go back to its specific placement in the factory preset, or would the mic placement go to default settings? Lot of things to consider.
I guess the band-aid solution would be to switch to the channel B cab which, if I remember correctly, is a legacy cab on all/most factory presets. That could be a backup in case the dynacab isn't the correct one or its empty.
Overall, if FAS comes up with a solution to this, I would LOVE to be able to switch out Dynacabs. I would certainly be more inclined to purchase Dynacab packs.
