DBA Setup for Weekly & Biweekly EE

We have deduction DBAs that are used for both weekly and bi-weekly paid employees. The amounts are based on 26 or 52 payrolls depending on whether they are paid weekly or bi-weekly. The employees had amounts incorrectly deducted from the 5th check in January. We would like to prevent this from happening in the future but since the DBAs are used for both weekly and bi-weekly employees can’t just change Pay Period 3 and 5 to “N” since weekly employees need pay period 3 to be a “Y”. How can we set these DBAs up to deduct correctly for both weekly and bi-weekly employees?
