BATTMAN as it is implemented in v3.5 is actually AutoCAD's ATTEDIT.
AutoCAD's BATTMAN allows you to edit a block reference's attribute collection, including the attribute TAGs and then ATTSYNC the block inserts without losing the existing attribute values.

If you edit the block using BEDIT (actually AutoCAD's REFEDIT) and change attribute TAG values then you lose the existing values of the attributes whose TAG you just changed.
This is a feature I use quite a lot. Do you have any plans to include it?
