Is there a way to change the datum of an existing ordinate dimension?

I'm using AutoCAD Mechanical 2009.

If the ordinate dimensions are created by AMAUTODIM, you can use AMPOWEREDIT command to re-arrange them.

Thanks, but AMAUTODIM is far too cumbersome for what I'm trying to do.  Each of my ordinate dimensions is connected to the base point of a block reference.  Going through the AMAUTODIM options to pick a single object nested inside each individual block reference is extremely tedious, compared to just picking each point manually.

I figured out how to do it.  When you select an ordinate dimension, it highlights the point at its origin, which can be moved.
