My current airline (as well as my previous one) solved this whole problem rather bluntly as reflected on the back of my certificate in the limitations section, which reads in part:
ATP CIRC APPCH - VMC ONLY
CL-65 ERJ-170 ERJ-190 CIRC APPCH - VMC ONLY
Besides, there are only two airports where we do any kind of circling with any kind of frequency, those being LGA and DCA, in the former case only if one is to consider Expressway Visual Rwy 31 a circling approach.
