In the Transactions tab, you have the option to Create Expense and Delete multiple transactions. Here's how:
To delete credit card transactions
Go to the Transactions page, then select the credit card transactions you would like to Delete. Click More, then select Delete.
To create expenses from transactions
Go to the Transactions page, then select the credit card transactions you would like to Create. Click Create Expense.
To Disable Matching
Go to the Transactions page, click TO DO then select the transaction that you would like to disable the matching. Click Actions > Disable Matching.
Note: A transaction with matching disabled will no longer appear on the to-do list of transactions.
This could only be done if the transactions are not yet matched to another expense.
