Bulk import cost for unprocessed cost

Summary:

can we do import cost for all transaction at a time?

or if that possible can we do import cost by grouping like same project number/project task/business unit at a time?

We created an unprocessed cost transactions from workato integration so there is much auto created transaction but we must click import cost one by one so it's too quite time consuming. Is it possible to import unprocessed cost with scenarios in bulk?
