FooEvents is designed to extend WooCommerce which means you can take advantage of thousands of third-party plugins that change the default behavior of your store based on your specific requirements.
You can add support for blocks/groups of tickets using the WooCommerce Min/Max Quantities plugin. This is useful when selling grouped tables or group discounts based on the number of tickets sold. Tickets can be grouped on an individual or variation level.
Please note the WooCommerce Min/Max Quantities can be purchased separately from the WooCommerce marketplace.
You can view a demo of a block/grouped tickets here.
