Set Default (or repeat last) For Move Action In Keynote

Using the move action in Keynote defaults to moving the object a certain amount of pixels to the right. I think it would be better if you could set the default action to move in a certain direction or a certain number of pixels. At least, if it would remember and repeat the last action. I do a lot of screen capture reveals in my presentations and I like to hide the bits I'm not speaking about yet to keep the audience in focus. It's pretty labor intensive to keep having to move the hide shape or screen capture to the left to center it again and then move it in the intended direction. Another option would be to not move it at all when you add a move (or other action). Why are you assuming you know what I want to do? :) Felix Unger taught us to NEVER assume.
