Reverse Advanced Many-To-Many Object Relation?

Hi.
Is there any way to create a Reverse Advanced Many-To-Many Object Relation?
I like the Reverse many-to-many relation dataype, but I’d like to have the same functionality for an advanced relationship, because I need to add som other custom field to define the relationship, but I also need to visualize the reverse relationship on the other side of it.
Is this something actually possible?

Thank you very much.

AFAIK not. You really need it to be bidrectional?

Yes, that would be really useful for the kind of objects we need to describe.
