Is it possible with Any Hostname?

Hello,

I’d like to ask your help. My client would like me to create one main website and three sub websites(on sub domains). Sub sites will have 99% of the content be the same as main website. Only the company logo and contact information would be different. My client would like to handle the main and sub sites from one control panel and wants new posts that was post on main site to appear on sub sites as well. Is it possible with Any Hostname?

Thank you.
