Ability to bulk update transactions in ARCS

Is there a way to bulk/mass update the attribute details for the transactions loaded into ARCS instead of updating manually one by one?

Transaction Matching file is sent from source and loaded into ARCS application. The TM file may or may not contains attribute detail(i .e Invoice Number). Note: The attribute (Invoice number) is not a required attribute in the match type

The use case is that there are more than 1000 of unmatched/supported transactions for a single account where invoice number is missing and user want to add invoice number for those transactions. User can add invoice number manually one by one however updating each invoice one by one will take a considerable amount of time, hence we will need the ability to mass update transaction that are loaded into ARCS
