Stress Coaxiality <-> Centered Groove</->

Hello;

Have any of you ever created a macro to switch from coaxiality to centered groove constraints?

I did a good look in the Solidworks API help but their examples are not documented and my level in this area still leaves something to be desired.
The general idea is to select my coaxiality constraints (because they are much easier to create and duplicate (copy with the constraints)), once my assembly is fully constrained I would like to be able to select all my coaxiality constraints to replace them with the groove constraints with the "centered in the groove" option. (and if it's reversible, so much the better)

A word to the wise...

No solutions envisaged for the 2014 version (according to Solidworks)....

I'll let it go for now.
