Media (video) duplicate check

[localsgaming]

I've had a few videos posted multiple times on listings.  It might be a nice feature to have a check at submission time for the exact same video url.  An error message could say "This video is already associated with this listing or may be pending moderator approval"

 

When the moderator is approving videos/images it isn't possible to see the existing content to ensure that the video being submitted is unique (aside from opening another browser window, which is what I am doing now).

 

Thanks!
