[Closed] unwrap uvw modifier – callbacks on move/rotate/scale?

hey all,
i have a request to make a tool for an artist for a workaround to what i would probably consider a bug…

add a uvunwrap modifer to an object and use the move/rotate/scale dropdown. set it to a different move mode (move horizontal for example). then select some uv’s and use the quad menu > move, or edit > move mode. it resets your move setting back to the first move mode, removing whatever specific move mode you were in.

i could easily see where this would get annoying for an artist, so i’m trying to find a way to preserve that mode – switching back to “move” would just switch to whichever dropdown you already had selected. however, i can’t seem to find any way to tie a script to those buttons. i can easily switch modes by doing [modifier].unwrap.moveh (for example), but i have no way to query current state, nor are they registered in the callback system anywhere.

is anyone familiar with another way to tie into these buttons somehow?
