KB 41529 indicates that the actual value of the name cannot be globally deleted. Being as this value does have a system ID number, is it possible that Blackbaud would consider creating a program similar to the "delete gifts" program which would accept the name of the query, require all other users to be logged out, and then delete these values based on type?

It is noted that if the site is locally hosted and has purchased RE:VBA, a simple program within a query will delete them (tested on Sample database and it works). It would even be possible to to add a selection criteria as a prompt for alias type. But, alas our production site is remotely hosted and we don't have RE:VBA.
