Hey, sounds like a neat idea. In some way can do that with tasks / to do, but your idea sounds much 'nicer".
I'd be happy with a Sync that worked ALL THE TIME.
Just added 1 picture and 1 name and changed 2 other names and added sources [Yippee!].
Sync "processed" but NONE of it is in the AMT!
Can't count the number of times we have "rebuilt" the AMT from our FTM at the recommendation of the support people.
Seriously - more detail, control and recoverability in the sync process.
