Yep, that's possible since Beta 3.

Here's the TCA settings that you'll need:
   MM_match_fields
	(not documented yet, but is exactly as used by DAM)
   MM_insert_fields
	(not documented yet, but is exactly as used by DAM)
   MM_table_where
	(not documented yet, but is exactly as used by DAM)
   MM_opposite_field
	If you want to make an mm relation editable from the foreign
	side of the relation as well, you need to set MM_opposite_field
	on the foreign side to the fieldname on the local side.
	E.g. if the field "companies.employees" is your local side
	and you want to make the same relation editable from the foreign
	side of the relation in a field called persons.employers, you
	would need to set the MM_opposite_field value of the TCA
	configuration of the persons.employers field to the string
	"employees".

cheers
