Owner/Initiator Homeschool Question

We are moving all of our current orders into the Owner/Initiator direction.  So the School would be the Owner, and contact teacher would be Initiator.  The issue I am having is trying to figure out how to make my homeschool accounts work within that.  Currently I don't have "homeschool" accounts, as they change frequently.  So their orders are under their name, and I had custom fields that were pulling the "school name" so I could check groups in.  However, once I switch to O/I then my custom fields will go away.  So I cant' figure out how to connect a homeschool group name (ex New Life Academy) to an order that is owned by the contact Jamie Newman.  I don't know if this question is clear, but hoping someone out there has dealt with this and has an answer!
