Linking Tons of Video from Many subfolders

I have to import a ton of concert fotoage from a bunch of cities.

Say I have 20 cities, each one has their own folder.

Inside each folder I may have several folders such as  Acam, Bcam, Ccam, gopro, drone, etc

Is there a way to link every .mov and mp4 in every subfolder, and knowing, where each file came from? 

In another NLE, I could just drag and drop all the cities, and all the subfolders would be created, but I want to do this in my favorite NLE Avid MC.

Thank You
