Business central - need help with reconciling bank statement

Hi, I setup two bank accounts in BC - B1 and B2.   B1 is linked to my bank checking account x1001.   I am able to import the statements and match with transactions related to B1.  However, I made a mistake in the register payment setup, where all my customer payments posting to B2 bank ledger entries instead of B1.  there might be about 100s of payments we might have registered/posted to B2 instead of B1.  I tried to link bank statement to B2 but doesn't seem to allow this.  I would like to get your thought on how I can do the recon. I would like to avoid having to reverse all the customer payments and register the payments to correct bank account (B1) and then reconcile. Appreciate your thoughts.
