I often find myself adjusting the C'bore depth of a hole to ensure we can use a standard length fastener. This means I have to measure the thickness of the part we're counterboring, and then set the counterbore depth accordingly.

Is there a way to just call out a counterbore depth offset from the bottom of the part so the length of the clearance hole (bottom of the counterbore to the bottom of the part) always remains a constant length regardless of the changing part thickness?
