# Mark many Pennylane bank transactions as having a lost receipt at once

Automatically mark many Pennylane bank transactions as having a lost receipt at once on app.pennylane.com. Marks a list of Pennylane bank transactions as having a lost receipt in one go, with the transactions list's bulk action, so they stop showing as waiting for a receipt. Faster than app.pennylane.com/mark_transactions_lost, which opens each transaction. With dryRun (default true) the bulk action is used but the change is held back. With dryRun false it is saved, then each transaction is read back. Returns, per transaction, its label, amount, date, whether it is still pending at the bank, its attached receipts and whether it is now marked lost. Up to 200 transactions per run. Fails when signed out of Pennylane.
