If you're describing a many-to-many relationship, the solution isn't
as simple as adding multiple fields. The current approach is to set up
the relation as a set of 1:M, using whatever is appropriate for the
current UI.
If you're describing a compound key involving multiple columns, that
should be supported. If it isn't, please create a ticket describing
the conditions to reproduce.
