User-specified Group activation sequence

I have 12 Somfy shades integrated via my Bond Bridge (RF transmitter) and grouped in various ways. When I lower/raise a group, I’d prefer them to move in a predictable sequence when the group is activated. It seems that if the group functionality already sends service calls in a certain order (e.g. alphabetical, ?), that the frontend could be updated to allow for user configuration of that order. I know I can do this in other ways, but (1) that only helps me and (2) then I’d have to bother with workarounds to properly program the frontend instead of just using standard and/or mushroom cover cards.
