We would like the ability to add multiple broken URLs to all point to a single redirect location as that would simplify navigation if a user still has an old URL.
Currently we have over 1000 broken URLs and rather than have each individual site owner take it down, we would prefer to just be able to bulk redirect all of them to a single page for simplicity.
It would also be convenient to be able to use a "wild card" for URLs that are very similar and should all point to the same place.
