add m4b edit ability to newer versions

I was hoping that V.2.82 would include the ability to edit M4B files, such as but not limited to:
MPEG-4 AAC (inAudible 1.71)
Nero m4b
AAC (LC) SBR
Lavf56.40.101
inAudible 1.78

Any plan to include these int he future?
At the moment, trying to edit these files leads to all tags being lost, an then having to manually edit them in windows explorer, one at a time...

thx
