Playlist : both USB drives

I have been trying to do this for days.

I have 2 hard drives, one attached to USB1 and the other to USB 2. (Lots of video files)

I am trying to create a playlist that has video from both drives.

After reading 100’s of posts, I understand that people are using relatives paths to create a playlist but only from 1 drive.

Has anyone been able to create a playlist that can play videos from 2 attached USB drives?

No as far as I know

I do not think this is possible, since the playlist must be saved in the same location as the files, so it  may not possible to make a playlist combining files from both drives.
