As of now, it is only possible to create one type of reflexive association (Relationship to the same object): Hierarchical reflexive association. (One to Many)

For instance, it is possible to create a relationship in an "Employee" object, to represent management (manages - managed by). This is a One to Many relationship as described bellow:

This "1-N" relationship is the only reflexive possible one.
We would like the ability to also have a "N-N" relationship possible.

Thus, not having a parent-children attachments but brothers attachments.
For instance, it is absolutely impossible right now in Rollbase to have a "N-N" relationship of items:

"An Item ('Article') is composed of other Items and can be component for other Items."

Thank you,
