Ability to Purchase Multiple Packages

Hi there, Merry Christmas! :)

1. I'd love to have the option for clients to purchase more than one package (I'm counting open floor plan as separate spaces for each functioning "room" within the open concept; also, I'm planning to offer a multi-room discount).
2. With the multi-room discount, is there a way for the system recognize if the discount code applies according to the number of packages they are purchasing? Is this possible?
   Thank you very much!
