Receipt Batch by Sales Office

Hi,

Is there any way to differentiate receipt batches by branch/sales office?  We need this to help bank reconciliation process at the head office as money is banked the next day per individual branch but a receipt batch may contain receipts from all branches, giving extra work to reconcile. 

Some of the batches are created manually and some are automatic.  The only thing I can think of is by creating a different receipt class for each.  Is there any other way?

Thanks
