Thread:Extension talk:Translate/Review link in diff pages

When I see a page showing in my watchlist I usually click the 'diff link' to see what have changed. From there I have no easy way to mark a translated message as reviewed. I have to find it manually in proofread mode.

I was wondering if the Translate extension could add a 'review' link to the diff page just like Extension:Thanks adds a 'thank' one.

I'm not sure if this should be requested in Phabricator or if it's something especially for translatewiki and therefor requested here or here.
