Ability to purchase multiple design packages in one transaction

It would be SO helpful for clients to be able to purchase multiple design packages in one transaction. I’ve had multiple clients try to purchase the same type of design package for multiple rooms, but it only charges them for one but still creates multiple projects. I then have to go in and delete the extras and advise the client to go back and purchase the other packages one at a time. It’s not a great client experience, and can be confusing to sort for both parties.
