How to link more than one revit file into project simultaneous, not need to link revit file one by one

[Anonymous]

Hi, friend, one question,

I am the Revit API learner.

Link different revit files to the project is really inconvenient, is there a add-in can link different revit files in to project simultaneous? for example, I am doing the MEP model, I need to link the architecture and structure model into current model by two times(one for architecture and one for structure）, whether I can link architecture and structure model by one time？

Could you share the code to me?

thanks
