Iterative Alignment issue

I have a part I have to do a iterative alignment on but the print only has 3A,1B, & 1C targets. The rotation is just 1 point on the top of the part on a plane lined up to the centerline of a cylinder on the opposite side. The plane is also called out as the B datum for a True position. Documents are controlled so I can't share it but is there anyway to rotate with only 1 target before I tell them they need to fix the print?

Thanks

By the looks of your sketch, I would simply switch B and C.
-Level to A axis(5 hit cylinder)
-Rotate to a 2d perp line 'ray line' from a axis to C
-Origin XY to A axis
-Origin Z to B
iterate

They are pretty picky and if a print has datum targets, that's how the program must be with only those points. But since the print has a separate B datum callout on the plane, I was able to convince them to let me add in the points so B has more than 1 point since I'll be measuring it as a plane later anyway for the TP B datum. Thanks for the suggestions.
