That job you have picked is just a Temporary Reservation, just go back in and talk to your recruiter, see if they can cancel it, just remember that if there are no other jobs in the system and then you want 92R back, it might not be there anymore, plus your recruiter can only pick a job and cancel it twice, after that its a phone call and a hassle to get another job picked. At least from my experiance.
Caveat on that, why didnt you look at all your other options before you picked that one? Was it your only option or did you just get talked into that one.
At least you should bring it up right away! Jobs come and go pretty quick.
