When rewrapp to AVID (Op-Atom) I had very often Comment --comment, different tag for music for example (Authors, track name, etc) --tag and source import --import to add metada directly in my bin in AVID.
For Rewrapp to AS10 : shim name --shim-name, add metadata from text file --dm-file.
in general I use disable track function --disable-tracks when I don't want certain audio tracks for example
BMX is very useful, It's too bad that the development was finished, it misses all news codec like DnxHR, XAVC-L, Prores, etc ...
