Possible to repeat previous steps in form without duplicating work?

What I would like to do is have a product request form on my site that allows people to add more to their order after they've chosen their first product. Is it possible to give an option at the end of the process that says "add more" and have it just take them through the whole process again without having to fill out a second form? How could I achieve this?

If I understood you right you refer to a shopping cart feature, like the user navigates through the website on different pages and ads products as he wishes, and finally click the shopping cart to checkout. Am I correct?

If this is the case I believe it cannot be achieved for now as it is a complex e-commerce feature. But if you specify more, or show us the site url or examples of what you are trying to achieve maybe we can get a workaround.

I apologize if I understood you wrong.

Let us know if we can be of more assistance.

Not totally a shopping cart kind of solution. Here's a form we had developed that has the functionality I'm talking about. http://lesolson.com/support/submit-meter-reading/

You can see where it says "+ Another Machine"

It basically just lets you repeat the previous fields over and over again as many times as you need. This is helpful when people are submitting information for multiple things. This way they don't have to fill the form out 10 times if they are entering information for 10 models. They just fill it out once and we just recieve it once.

Does that make sense?
