Student Self Service Payment

Hi,

As per the delivered function, though self service a student can make payment based on the below options

a. By Business Unit

b. By Term

C. By Charge.

Is there other way through which we can allow the student to make payment through self service based on both Term and by Charge. Ie few items based on Individual Charge and the rest based on Term. Or the other option is to allow student pay based on account type ?

Thank,
