student finance - bank details

just a quick question.. i've had all my offers back and ready to apply for student finance but havent done so yet as i have an appointment tomorrow to set up another bank account. my main reason of this was because i wanted to keep my savings separate from my loans and i cant pay out by direct debit in my current account. anyways, does anybody know if i set up my student finance now and put my bank details in for the account i have now, can i then change them to my new account that i'll be setting up tomorrow? or have i to just set up my finance when my new details come through?
