Having trouble reusing an old page two attribute

We are trying to reuse an old page two attribute that's been shutoff for about a year.  When we try to reset the list of values, we cannot because of existing saved queries using that old attribute.  I was able to create a query which shows the user who owns the query (personal saved searches as well as saved global searches cause this problem).  Updating that query does work.

The big problem is that Agile is only telling us about the offending queries one at a time.  We fix one and then another one pops up.  I'm looking for a way to identify ALL queries using a specific page two attribute.  Does anyone have a sample query or method to do this?  If we have to contact two or three users to update an old query is much different than knowing going in we have 50 different queries causing problems.
