Any way to change the due date for a batch of bills

I have a group of bills in the system that all have the wrong due date.  They are pending approval.  Is there a way to select this group of bills and change the due date across them?  At the moment I have to open each invoice, put it back on hold, edit the due date, save the bill, and then send it on for approval.

These bills have been generated through the holdback release process of the construction module.  The system seems to be taking the vendor terms and the invoice date to select a due date.  But, for these bills we have a separate due date that is 55 days after completion of work.

This process often generates groups of dozens of bills at a time and it takes a lot of time to change it one manually.

Thanks in advance.
