While there is a way to create individual clinician invoice price settings that override the defaults in the account, there isn't something like that for superbills (or for units of superbill). That would be a helpful feature: when there are different unit amounts being billed for different people in the same practice, this feature would limits the risk of clinician/user error when inputting information into the superbill after a client visit, and wouldn't require me as a supervisor having to go over all the superbills closely to make sure there aren't unintentional errors before they are submitted.
