Feature request: Ability to add multiple sounds at once

[tmdag]

After upgrading my fedora system 38->39, Blanket removed all my added sounds, erroring one by one that file is no longer accessible (not sure why, as files are exactly at the same location as before).
As I have added quite a lot of sounds, its quite annoying that i have to go one by one and select each one of them, again. So it would be great if we can load multiple files at the same time.

Also, there should be a check whenever you are loading same sound twice - as currently this is possible.
