In the card queue I often see two cards being generated for an Individual Membership and then a note next to it letting us know not to issue the card.
There's a quick and simple way to tell PIMMS not to issue that second card when you are first entering the payment.
In this example the card for Janet will get issued and although PIMMS has set up a card for Robert I've changed the "Assigned to" dropdown to "Do not issue".
When you save, only Janet's card will go the queue.
In the second example Ulrika's card will get issued, and Stan's won't. It doesn't matter the order that the cards appear in the list.
