Changing spindle phasing or threading phasing

Greetings,
I am currently setting up a very complex part on my Mazak HQR-150msy. The part I am cutting has very precise timing between an internal, external thread and milled features. I have the timing of the two threads set, but I now need to orientate the milling to the thread. I have a shaped collet in my sub to grab the part. My issues is that when I rotate all of my milled features, I will no longer be in synch with my sub spindle collet. How do you adjust the phasing of the sub and main to re-establish proper orientation or can I adjust the phasing of my two threads to get them aligned with the milling. I cannot find any information in the manuals.

Thanks,
Doug

My setup guy may have figured this out. Once we are sure, I'll post what we did, so if anyone else has this same issue they can do thee same.

This is our transfer routine. If you follow down the program, we engage the sub spindle c axis and position it to where we want. Both spindles synch up from this position
