BTP: Allow Customers to Create Multiple Packs in one a Single Order (Yes by default) shows an Add another pack button so several packs can be built in one order. BTP: Allow Customers to Modify Quantity of a specific Pack (Yes by default) lets the quantity stepper on a pack multiply the whole pack. Note that in the current version the stepper and the per-pack Delete button on the BTP page are drawn using the Custom Meal Builder versions of these two switches (CMB: Allow Customers to Modify Quantity... and CMB: Allow Customers to Create Multiple Packs...), while the BTP switches control the Add another pack button and whether the entered quantity is actually applied - so if the page looks inconsistent, check both tabs.
