Unique Door Marks for Multiple Instances of Linked file

[veritably]

Hello, 

I am working on a school project that has 3 instances of the same classroom pod group (which we made as a seperate Revit file, linked in 3 times to the master file). To get unique Room numbers, the rooms for the classrooms are inserted in the main model, not the linked file.

But I can't find a way to get unique door marks for each instance of a classroom pod. The doors have to be inserted in the linked file (eg. door mark 101), so when looking at a combined schedule in the main file, there's 3 instances of door 101. Ideally, these would all be different marks. The best idea I have is to make dummy door tags with a dummy prefixes different for each pod. But this does not translate to a schedule, in which I have to make a different dummy variable based on Link:Name.

Any ideas?

Thanks!

edit the door tag family and add a prefix to it of the link name. going to see i can do something like this now

This worked great and is way easier than the correct way to have multiple door tags from a single door of a linked file.
