Circular reference between a shortcut and the entitie in one and the same model

I did some moving of diagrams and entities recently between CDM’s in Sybase Powerdesigner 15.3

And I discovered I ended up with some double entities (one base and a shortcut one referencing to that base entity in the same model).

Anyhow: I like to know if there is a way to merge the entity and its shortcut into one again (without breaking shortcut references to other models).

Thanks a lot in advance,
