ManyToMany mapping + additional fields in association table

Question

I have two models Entry and Entrant which has ManyToMany relationship with annotations. While generating the DDL Ebean adds entry_entrant table which contains fields for mentioned models' IDs.

In general I need to extend this table, to add fields for ie date of creation of relationship or user who added the relation.

Thanks in advance, biesior!
