Can you prevent the use of a certain expense type by business unit

Content

The expense type of "Tuition Reimbursement" is not valid for one of our Business Units and we would like to restrict that unit from being able to use that expense type so that they can no longer accidentally charge that to that account code.  Is that possible?
