thats already available? (the mission waypoints)
like
/laɪk/ [lahyk]
–adjective
1. of the same form, appearance, kind, character, amount, etc.: I cannot remember a like instance.
2. corresponding or agreeing in general or in some noticeable respect; similar; analogous: drawing, painting, and like arts.
3. bearing resemblance.
On a serious note, I agree with the OP. It'd be nice to have, but not worth the GUI overhaul that would likely be needed on its own.
