Our community would like the ability to be able to put a thread into multiple categories. (This might need to be moderator and above privilege).

I'm assuming this is not currently possible. Would it be possible to add this, whether in the core or as a plugin?

I'm not quite sure what the current db schema looks like. I understand everything is just in a single collection. Would it be as simple as having some kind of interface which ads a linking between a thread and a category, or is it a huge lift?
