POS Tab Builder

Our POS is used for our proshop but also our lounge & cafe (beverages & snacks).   We often have tournaments / events lasting the entire weekend.  Would be amazing to be able to set up "tabs' for players to build / add POS purchases over an evening or weekend so that the tab could be settled at end of the event / weekend.  My suggestion is, allow a cart to be named & saved, then recalled to cash out! :)
