invoice with both exempt vat and 20% vat items- can I justify as 1 transaction

I frequently invoice bills with both a VAT exempt item and a 20% vatable item on them as 1 transaction.

when justifying this income in the bank account on clearbooks is there a simple way of splitting this bill in the bank breakdown as 1 transaction with the 2 varying vat rates. at the moment I am having to enter each part of the bill separately which confuses things and takes longer. I used to be able to do this on a previous accounting software programme.
