Mirror of Familty Table Instance

Hello,

Creo 2.0

I have created a mirror of a part. Because the parent part has the P/N engraved, I add a family table to the parent with a lone instance with _MIR suffix and with the P/N feature suppressed.  I use the _MIR instance to create my mirrored part.

The problem is that the mirrored part will not regenerate with changes to the parent unless the _MIR instance is opened directly.  If I make changes to the parent generic and open the mirrored part and regenerate, the changes are not reflected (see what I did there 😁) in the mirrored part.  I have to open the _MIR instance.

Is there a way to have the mirrored part automatically open the _MIR instance to check for changes?  I'm afraid that changes aren't going to get propagated to the mirrored part.
