Linking a custom Catalogue Item to a Custom Family/Part

Hello Community.

I am having trouble figuring out how to link a custom Catalogue Item to a Custom Family/Part

I created an Object from a Compound cell and added to the Data Set Catalogue by using ‘Paradef’ BXC file. I have added some definitions to it and it works great. I then created a custom Family and parts XML and defined the Level to be used.

How do I link the Catalogue item (Object) to the Family/Part so that when a BIM modeller select and places the object in a model, the family & Part is pre-defined, ultimately ensuring the correct level is used. Currently it places the catalogue item on the active level.

I am using AECOsim Building Designer CONNECT (Update 3)

Thanks!
