If you have really high Craftsmanship you might be able to finish with a Standard Synthesis instead of CSII. At 874 craftsmanship my CS2 does 357/431 on Adam Nuggets so you're probably gonna need around 900ish craft. You'd need to fit in 15 CP but this would likely cut down on your quality. That aside, I do what you do and manually hit a second CS2 for this stuff. It's annoying but gets the job done.

EDIT: Actually, after mathing it out, you're gonna need about 1055 craftsmanship... yeah. Not yet unless you include ING2.
