Is there any way to delete Unprocessed cost imported from Payables from Project Unprocessed cost

Duplicate transactions are imported into unprocessed project cost area. We want to delete any 1 batch and import other. But as per PJC: Unable To Process/ Delete Rejected Supplier Invoice Transaction Getting An Error PJF_CAL_NEVER_OPEN_GL (Doc ID 2202755.1)

You can only delete the rejected or all the unprocessed cost transactions from the Manage Unprocessed Transactions page by clicking Delete Cost Transactions for non-seeded transaction sources. Deletion of transactions belonging to Oracle Fusion Payables (or any Seeded sources) is NOT allowed via this function.

Pls advise is there any alternative way to do that
