How do i pay mulitple invoices under the one supplier with one single bank payment which has been imported through live bank feed?

Hello Rsmithphe, 

Welcome to the Community page, 

You should be able to match all the invoices off to that payment asl as long as the information is the same so the amount, account, and date it will find a match. with the amounts being different as they all add up to the one amount when you go to banking page>click on the transacton>find match and tick all the invoices that relate to that payment then >save this will then match them all up and move the transaction from for review to categorised.
