Marketpress - Possible to add multiple items to cart in one click

Hello.

I'm trying to set up a Marketpress site which selects a number of products for the user depending on some input from them, then displays these items on a page. Ideally I want the user to click one button which sends all the items to cart in one go, rather than having to add each one to cart separately.

Is this easily possible? If not, do you know what would be the best way to accomplish this?

Thanks in advance!
Neil
