I am having trouble using the hole series feature with existing holes.  I have an assembly with many different parts. In a particular section of my assembly I am trying to create a hole series b/t a stack up of three parts, one of which already has two tapped holes I want to use as a starter. I've set up the "use existing hole(s)" to "as: end". When I get to the next tab "first part" it will not let me select the face that I want to put the counterbore. Does anyone have a solution to this issue?
