Multiple domains under one account

Can you have multiple domains under one Editor X site like Wix has? Here’s a link to the Wix info if you are confused about what I mean.

You can.

Can they be both, sites created in Wix and Editor X or only Editor X under one Editor X hosting plan?

@graphicdesignertms What would be the setup? This article might help to understand the idea of having multiple domains.
Sounds like if you want one domain to be a Wix and another to be an Editor X site, might be looking for a subdomain.
