When a new vacancy is bid upon, do you have the option to opt to your 2nd choice.

Lets say I bid for base A, but dont like where I fall, can I say I want my option 2, base B because I would hold higher seniority there? I would prefer A, but after the first award of the vacancy B would be better after seeing where everyone else falls. Even though I may be based in base C, which is my 3rd choice on my bid.
