Is there a way to put a thread prefix in the URL slug?

[Mike Fara]

I have isolated places where videos are embedded on the first post of certain threads and pre-fixed them as "VIDEO". This is sufficient enough that VIDEO will appear in the title of the thread, but for the actual URL slug/URL itself, video is not present. Google's algorithm apparently requires video to be in the URL itself to index that type of content as a "VIDEO" result. Any suggestions?
Is there a way to put a thread prefix in the URL slug?
