Yes you most certainly can.
With the website, it should save everything you enter all the time. But it's still a good idea to use save &sign out just to make sure that nothing is lost. That is in the My Account drop down menu
When you do this the site will send an email telling you that you are not done. These tend to arrive long after the user has returned and finished. Figured I'd give you a heads up on this, it causes understandable confusion.
