Extension for duplicating items with options on one page

This is a bit tricky, and I can't find an extension to do what I need to do.

Customer selects a product, customizes it with options including engraving, accessories, etc.
On the same page:
Customer clicks "Add Another" button
Another group is added below on the same page with new options set for second product
Duplicate as many times as needed
Add to Cart then adds all of those as individual line items that can be edited.

So the goal is to allow the customer to add as many duplicate items to the cart as they wish, each with their own options, and do it all on one page.

Is this even possible? Is there an extension that would do this? Thanks for the help!

Cannot be done with Opencart. Exept, if you are wealthy anough, to get it made, BUT, it'll take a real Pro.
Good Luck!
