Medial library for external drives only (LIVE HUB)

I have a live hub and wish to compile a media library only for the 2 usb’s that are plugged in however the option only lets you do 1 usb or all locations which includes the internal drive as well. Does anyone know how to compile only external drives. My goal is to see all my movies in one complete list instead of having to go from usb 1 to usb 2 to see my movies. Any help would be great.

No, I don’t know of a way to do that, but what’s the problem with it compiling the INTERNAL drive at the same time?
