It is now possible to automatically create a transfer cash transaction, within your cash account with a filter.
An example of how this can be used is with an ATM cash withdrawal as a transfer from your bank account to your cash account. You can use a filter to match the merchant name of the cash withdrawal from the ATM in your bank account that then creates a new transfer transaction in your cash account with the matching amount.
