JDE - Automatic Payments: Next Payment Number while writing a check

We have an issue with the next payment number while writing a Check in Automatic Payment.

We have a number of companies and Business Units in our system. Each of these business units have their own Bank Account ID (AID). However all these Bank Account IDs have the same Transit Number (TNST) and Bank Account (CBNK) in P0030G since all these business units are using the same physical bank account.

Even though we have defined different Next Payment numbers in P0030G for these different Bank Account IDs, when we write the checks for the different business units at the same time by selecting all, the next numbers for all these different bank accounts get updated with the same number.
