Custom Main page

Hello
I’m using S2member pro version, and I need to do something with my website I’m not sure if it’s possible after watching all tutorials,
I want the website main page (as a non member) to appear as a sales page where I put the features of my membership website, and when the user sign in the main page changes to another different page (the blog).
is this possible ?
Thank you
Regards
