Portals per type

Nothing very problematic, this is mostly a quality of life suggestion you can put very far in the priorities ;), but it could be nice to add portals that are from another category than the current portal. Currently when I select where the portal come from, I have 36 different choices but half of them are from the wrong category.

Example "Exit" Object portal can only see object portals.
