Inserting individual pricing per class/student for same Transaction detail

When entering in different pricing amounts for the same transaction (example, costume fees or snack fees, where the Transaction detail is the same, but pricing would be different per class/student) could you include a column to hand type in the debit amount of the transaction, without having to go into each class/student and do them one at a time? For instance, if you go to to the costume manager and add a costume fee, the information is the same for each class ("Costume Fees" (class name) June Recital", but the pricing would be different per class. An additional column to enter in the pricing of each costume (per class) without having to go into the class individually and repeat the process numerous times.

We often do this with snack/concession charges as well. If there was a way to make a general debit charge for students for the same line item but type in different amounts per student, this would save so much time then having to go into each dancer's account individually and insert debit items one at a time.

thank you!
