Payables Accounting Process

 Does anyone have experience with automatically populating the period ending dates from the payables periods within the payables accounting process?  We have many ou's and need to run the payables accounting process several times per day in each OU.  It is a very long process to have to reset up these processes when the accounting period changes.  We would like to be able to automatically populate the periods beginning and ending dates from the payables accounting periods each period including the ability to have the periods automatically change once the accounting periods change. 

Any comments of experience with being able to do this is welcomed.
