Pitch Circle Diameter(PCD) inside hole note callout

Currently using Creo 7, We have a standard hole note that we use all the time.

&PATTERN_NO - &METRIC_SIZE &DRILL_DEPTH
EQUI SP ON A &d PCD

6 - M4x0.7 Thru

Equi Sp on a  PCD.

The default hole callout can do all the parameters apart from the PCD. For this we have to find the driven dimension for the diameter and copy that parameter into the hole note text.

Often our models have multiple hole patterns so we can't set a parameter in the model start-up.

Is there any parameter that can be used like PATTERN_NO. but for the axis diameter?

If not is there any work around so that the ID of the diameter can stay the same relative to the hole that it was created by?
