Application Express :: How To Manage Positions Of Different Display Points Of Theme

I'm developing, or trying, on Apex 4.2...The issue is about themes and how to manage the positions of diferents Display Points of a theme.

Everybody know that any theme have a map where its position all differents parts of this map (Body1, Body2, Body3, position01, position02 and so). So when you choice any theme, it come with all this Display points defined. You can see this map rendering any region page and in the item Display Point you can see this map clicking on the light.

There is anyway to can manage this map and change position or behavior of those points?. For example , I'm interested that under the tabs, to have at the same height, 3 diferentes position, one at left, one at center and other at right.
