Ordinate dimension-Change origin question

[CADone]

I have a drawing file. The view consist of a rectangle (Plate face) with several circles (Holes).

On my drawing view, I need to use a ordinate dim. My origin is in the center of the plate. I have ordinate dimentioned all the holes (ver and hor)

Needed change :
I want the odinate to be changed from the center to Lower left corner of the plate.
Now, is there a simple way of doing this without I having to redo all dims?

CADone;
You can pick the end of the witness line on your zero dimension and drag it to that edge. All other dimensions should update automaticaly.
