You can do this in the post (I've done it) but I forget what I had to do. I don't remember it being particularly difficult, however.
Work thru the logic - procs, block templates, etc.
One other thing - note that NX typically moves to the first cut depth, THEN sets up the G71 cycle. The cycle assumes you are at the OD, and adds ANOTHER cut depth, so the first pass is twice as deep as you want. Not sure if they fixed that yet, but you should be able to figure it out to get the right X values.
