Add item to already paid order

How do I add an item to an order that's had been paid, the funds are still on hold

You don't, it has to be treated as a separate transaction. If the first order has not been shipped, you could combine and refund extra postage updating the tracking number to match for the other item. Funds on hold would not come into play, they are for the first item only so could not be added to for both transactions.
