How can we assign multiple interest charges on system Option>Trans and Customers tab?

Hi there!

We have 3 different Late Charge Schedules setup in A/R.  They are used for specific Trx. Types that are used to bill specific Customers who are grouped under 3 different Profile Classes. For each 3 Late Charge types there are 3 different Adjustment Types defined ( All 3 adjustments are based on Activity GL account and are set up with 3 different GL account string.

For example:

1.) Customer Name=> A

Profile Class tab=> Profile Class: XX

Late Charge tab=> Interest Charges region> Charge per Transaction and Late Charge Schedule:X1. => Interest Charge Schedule is based on  a Flat Amount of $20.00 and will be Charged on 6th date after the Due Date of the Transaction and end of the month on the remaining balance of each unpaid Transaction. Penalty Charge Schedule is Blank
