Constrict Helix Bore Size

[Steinwerks]

How can I restrict a helix bore so that I do not get a slug in the middle of the hole? Basically I have two holes in my part that I want to helix into and then finish the diameter, but I'm wondering if a pocket routine may be the better option with a finish pass and a helix entry. In which case, is there an easy way to center the helical entry on a circular pocket?

This can be done quite easy by going to the Passes tab and selecting Multiple Passes

Well I was definitely using the wrong path. Basically I'd like a way to mill a round pocket and have the tool helix in the center of the pocket without having to fiddle with the Ramp Radial Clearance. Mastercam had a centering checkbox that just put it on the center point of a circular pocket and I was hoping for a similar solution, but asked the wrong question.
