Display Managed Metadata field parent of selected item

Here's the example. A school district has a single system to assign aids to grades at different buildings. You have school A, B, C, D, and E all with classes 1, 2, 3, 4, 5. You have a form to assign the aid to the class on a certain day. The issue is that the aid does not know which school to go to because all the form says is "1". Is there a way to get the result to look like "A - 1" from the Managed Metadata field? I also tried cascading dropdowns, but the same names still cause issues in selecting since you can select multiple schools and classes for a single day and I really do not want to have all those extra fields if I do not need to.
