Are composite PKs/FSs supported?

Are composite PKs/FKs supported in DomMin.Sync?

Our need would be to filter the syncronized data by a value in another table, but the relation between the two tables are defined using a composite key.
AddJoin()..On(x, Id, y, IdForX) method looks to support only one condition, something like
x JOIN y ON x.Id = y.IdForX

our join condition looks more like:
x join y On x.Id_Part1 = y.IdForX_Part1 and x.Id_Part2 = y.IdForX_Part2.

Thanks a lot!
