GROUP ORDERS TOGETHER BY CUSTOMER

[balsam]

I'm looking for a plugin to do this:

Our customers are going to place multiple orders for each of their staff based on name, with a separate invoice for each one, for their staff members to double check. However, we want them to be able to 'Group' their orders together for the purpose of issuing a payment to us for the totals. We also want Virtuemart to issue a printed 'order' that is a summary of all the others the customer selects to group. So here's what i envision happening:

1) Customer places several orders and checks them out (Lets say 3 - Ryan, Steve, Jon). The customer gets 3 different invoices / order confirmations from the site, with the name as well as what product was ordered for that person
2) Person goes to some page, clicks on all 3 orders, and picks 'Group'  or something like that. They consequently get printed out an order confirmation that sums up all 3 orders, with just a little comment line as to who is on the 'order' (so if Ryan orders 2 tshirts and 1 sweater, Steve orders 3 sweaters, and Jon orders 2 t-shirts, it spits out an order for 4-T-shirts, 4 sweatshirts, and lists the names Ryan, Steve and Jon.

This 'grouped' order doesn't HAVE to exist beyond simply being a print out - it would be nice if it got remembered, but really, we just want them to be able to print a total order of things they pick.

Does this plugin exist? Or are there any recommendations as to how to do it?
