Deleting metadata input

Folks,
I've been honing my cataloging skills; and I've got a good pattern down. One thing - I've input some "location" metadata inputs, and I don't want to keep them. Is there any way to batch remove them without removing all the other inputs that I've created?

Thanks.

Also, has anyone else noticed the inability to filter on the "location" metadata? Kind of why I'm trying to get rid of it in the first place.
