Like mappings use wildcard characters: asterisks ( * ) and question marks ( ? ). Asterisks are placeholders for any number of characters. For example, 1190* maps the accounts 1190, 1190100, and 1190-200 to the Cash target account.
Question marks are placeholders for one character. For example, the source account of 119? maps only to source accounts that contain four characters and that begin with 119.
