Problem Changing drill depth in Nesting

Hi everyone

Back again with another drilling problem in nesting. My problem is changing the depth of drilled holes of the same size, I have two parts both with 4 holes and want 2 holes thru and 2 holes blind. I have looked at the Help topics and does not seem to address this issue. I can solve this by changing 2 of the hole diameters by .001 and it will give me another tool or edit the Gcode and add another Z value but that's not addressing the real problem. If there is a way to do this I would appreciate your feedback.

Thanks Keith
