Sage Bank Feeds

Would it be possible to design a feature within Sage 50c Accounts, so I can create a rule within Sage Bank Feeds, which applies to bank transfers? I am trying create a Bank Rule within the Sage Bank Feeds window. Before I can save the rule, I need to add the accounts which the rule will assign to. The transaction is a transfer & it will not let me select the bank accounts involved on the nominal list. I have asked a Sage Ambassador and they advised it is not possible to create a rule for a bank transfer. My client has a large volume of Sagepay transactions received which are automatically posted to 1216 and these need transferring across to 1200.
