I don't think so. Normally you would have a fixed cup which is tightened up to the BB shell, and an adjustable cup with one lockring which is adjusted up to the shell when the adjustable cup has been adjusted-- if that makes sense.
This doesn't apply for Shimano sealed BB's in which case they are both effectively fixed cups.
