Can we get GameMode::ResetLevel() exposed to blueprints in 4.3?

RIght now, I have to know which level I’m currently playing, and reload that level explicitly, to reset to the beginning. And, if I want to manage memory, I have to do that through a transition level, too.
Can we get the GameMode::ResetLevel() function exposed to blueprints for 4.3?
And, longer term, can we get some kind of checkpoint support? (I suppose I can “save game” to some dedicated slot, and “load game from slot” on the checkpoint slot, as a prototype version of that.)
