Copying families from one model to another

[alaa.farhat]

I am an electrical engineer and need to insert families into my model without losing the host parameter 

so I created the same structure of the linked files with using the same models in both files , and tried to group the lighting families and copy them into the second model , but grouping and copying will make the families lose the host.

Tried also to copy monitor the lighting families into the second model and each time the host is removed , is there any way to move the families from one model to another without losing host??

It would be easy if you didn't use hosted families. 

If you are hosting to linked elements, I don't think you can accomplish this without a third-party solution. Even if you were linking the same model, Revit sees it as a different link.

Rob is correct. I had to resort to dynamo to accomplish this task in the past. I still ended up losing much information.

Are you using host-specific families or workplane/face based familes?

[alaa.farhat]

I am using face based families , since we need to keep the families connected to it's host whenever the other disciplines (Architect , Structure,..) decided to move their elements

[alaa.farhat]

I thought of Dynamo but not sure if it will do the job and not aware of a script that might do the job

oh so even using Dynamo wont be helpful
