Find all the pages having a particular slice?

[dan.duett]

I asked a similar question a while back. I was simply looking to find every document using a particular slice (without refactoring) but someone on the Prismic team pointed us in the right direction with a sample script:

Find all documents that use a particular slice?

Hey, Prismic community! Is there any way to find/query all instances of a particular slice across published documents? We're looking to retire/replace certain slices across hundreds of documents; we don't know whether they're being used anywhere, and if so, where. It looks like this has been requested before (please add another vote to the tally for me). Ideally this could be done via the UI, but if there's a more technical option in the meantime, I want to know about it!
