A quick fix update
As of v16b, Shift and select "snap to grid" will only snap the pivot point to the grid. The older set up snapped both the pivot and the CP.
To only snap the CP's just use the "snap to grid" with the CP's selected.
Okay... that should be very useful to me.
Of course, don't forget that in order for A:M to save the Pivot settings they need to be part of a Named Group.
Thanks for the heads up on this... and for the original Tutorial Jason!
