Product Add-Ons for WooCommerce

When you add a product level add-on to a bookable product there is an option to multiply the cost of the add-on by persons/blocks as seen here: http://cld.wthms.co/1dc2x/1rEWPCQi+

When you add in a global add-on there is not the same option available. This means that if you are offering a large number of bookable products that all offer the same add-ons you’d have to add each one in at the product level as opposed to using the global add on option.
