Parents choose what they pay for

When my parents log into the parent portal to pay tuition, they have two options, Pay balance, or pay all overdue Items. But If were to prosses a payment, It gives me balance, or tuition. It would be very useful get the Tuition only button to appear in my parent portal. This is important now, because I have comp fees that aren't due, but Tuition is. My parents are not able to complete online payments due to this.
