I know it can be done, I do it, but it's still a pita.
Oh, I don't recalibrate for every shot! I usually find the max-polarization position and leave it there. Exceptions:
1) I most commonly use CPLs on very fast non-A-type lenses like the Vivitar-Kiron 24/2 (with iris blades stuck wide open) or my K50/1.2. I'll in sunshine with with CPL on, adjusted so my K20D's shutter stays below the flashing 1/4000 second warning. If I go into lesser light I either switch to minimum polarization or just remove the CPL.
2) With a CPL on slower lenses, I only adjust polarization to accommodate the shutter.
