In the Clover Dining app, allow a partial payment to be applied to a tab and leave the tab open for more orders and have balance paid later.

Use Case:
A group has a tab open. One person from the group has to go and wants to pay either for specific items or a specific amount towards that tab before leaving. The rest of the group is staying and will continue to order drinks and food.
Currently, if a payment is applied, you can no longer add items to a tab.
This makes it very complicated to continue to serve customers who don't want to have to run their cards to close the current tab when one person decides to leave, and open a new tab to continue to order and then pay again later.

Please add this ASAP
