Is there a way to link the Tap Thread Depth to a global variable or to thread to surface?  When selecting Up To Surface as the End Condition for a threaded hole, the Tap Thread Depth has only one selection Blind (2 * dia).  I can manual input the depth if i wan't but it doesn't seem to let me link to another dimension like through a global variable.

Am i missing something or is that simply not possibl
