Is there (what's the most efficient) way to mass delete Global Value Set values?
Removing/Replacing them manually one by one in the UI is not acceptable. I thought I might be able to do it via destructiveChanges with ant, but I am not sure if you can specifically delete certain values and not the whole set.
I also thought about deleting and deploying again, though it's a bit too late as it's referenced by quite a few picklists in the system.
