As it stands, when playing with a controller, I can press "X on a target to bring up the menu, choose "mark", and then designate which mark goes on the target. When that is done, I'm still in the window with all the marks, and have to close it out, move to another target and open it again.

It would be far easier if the mark window closed after a mark is designated, that way a tank using a controller can quickly flip to the next enemies and do it again.

Another way of improving marking on controller might be something where the cursors cycle enemies automatically upon designating marks, while the mark window stays open until you close it.
