Multiple Foreign Keys on creating table shortcut

Hi,

I have 4 facts on my PDM which are snow-flake in nature. As It's a snow-flake schema I've parent-child dimensions say A and B, where B connects to the fact table. These A and B are in all 4 fact Snow-flakes, so I've created SHORTCUTS for A and B from first snow-flake and used in other 3.

Problem : The issue now is, that PowerDesigner is creating 4 FKs from A to B for the parent-child relation, where ideally it should show just 1, as others are just shortcuts of the same dimensions.

I'm looking for a solution to merge these 4 FKs in 1. Is there any simple option in settings, rather than reworking on the diagrams?

Thanks

Akhil
