Add Listing Form -review Listing before publishing

When the data requested have been introduced by the useres in the Add
Listing Form, the user has to click on the button Review Your Listing
and below there is note stating:
Note: You will be able to see a preview in the next page

Then we get a new page with a Preview and then the user has the chance to
go back and make changes or go forth and publish the Listing.

Is it possible to just skip these chances, skip the Preview page and
publish the Listing at once?

If it is, my guess is that the code needs be changed; if so, please let me
know which file needs to be changed and what do I have to write as
precisely as possible.
