Move loop in point?

[dodge]

Can't figure out how to do this. Moving the end point is simple enough, but what if I make a loop then want to move the in point backwards or forwards?

Traktor by the way.

Thanks in advance

I don't do it often, but if I need to I'll go to the move button above cue and grid and move it from there by selecting loop and the value, obviously it moves the entire loop in the usual values but I'm guessing that's what you want to do right?

No, I literally want to move the beginning point of the loop not the whole loop. What I am looking for is what "add in" option I should use in the controller mapping section. Tried all of them but can't figure it out. I might be missing something simple
