Multiple interunit accounts

Is there a way to use more than one interunit debit and credit accounts based on the values in the Legal entity? There isd a client that uses multiple due to and due from accounts in their Chart of Accounts. That financial structure must be balanced but there are several debit and credit accounts that they use to do this. For example

18111 - Due from Unrestricted Fund

181112 - Due from Restricted fund

18113 - Due from State Fund

28111 Due from Unrestricted Fund

28112 Due from Restricted Fund

28113 Due from Sate Fund

These are all in a single legal entity. Does anyone have an idea how to set it up?

Thanks,

Amy
