All Eftpos sales and refunds are done as one transaction each day, not sure how to process these in Reckon Accounts

With Accounts Premier 2017,,,

All Eftpos transactions (sales and refunds) are processed as a single transaction each day.  I currently match these in the online banking center by making a deposit from the Undeposited Funds account to the bank account.  I issued an eftpos refund for the first time though and am not sure how to process this.

The refund came from a credit/adjustment note, where I used "Use credit to....Issue refund".
Of course Undeposited Funds is not available to choose to issue a refund from, so I am unable to create a deposit that matches the total figure for  the day.

Does it even matter if they can't be matched seeing they will reconcile with the bank account anyway?  As per the last post here...

I seem to remember transactions staying in the "Match Transactions" window though until they are matched with a single transaction, or do they disappear once reconciled?
