Create daily returns batch

Hi guys,

We are using the Returns Module purely for processing sales returns and presently ever RTN document gets placed in a single  batch called "CREDIT"

This causes issues everyday for posting.  What I would like to do is set up a daily batch based off the day before's date.  So if it was the 10th of February then all of the returns entered on the 9th would be in batch "02/09"

Any help would be greatly appreciated.

Thanks,

Heath
