Submit listing-all steps in one page

Hi guys,

I would like to ask you how can I make a single page for submit listings including all steps?
I mean now there are 6 steps and you have to click continue after every step but there are 2 problems:
1. There is no Back button and you have to use browser’s Back button if you want to go back for any reson.
2. After last step (step 6) when the listing has been submited, if you click browser’s Back button you get back to step 5 and if you click Continue (from step 5), you will get to step 6 so another listing submitted (a copy of first one).

So what I want to do is to make a page for submit listings and to integrate everything in one page with a only one Submit button at the bottom of the page.

How can I do that please?

Thank you!
