Threshold limit for approving Intercompany transactions

Business wants to route Intercompany transactions to specific approvers if total amount of all transactions for combination of provider and receiver organization and a particular Intercompany transaction type breaches the threshold limit of 1 million for an accounting year.

For example, if lets say there is Intercompany transaction of "Loan" and "Interest".Lets say Provider Org "A" is giving loan to Receiver Org B and transaction amount is 100k and if sum total amount of all transactions with transaction type as Loan for current accounting year provided from "A" to "B" exceeds 1 million then only it should to approver X else transaction should go to approver Y
