Hi there I am confused about what you are talking about

I have a custom docs subdomain set up using CNAME and now would like to also add a status subdomain to another repository on the same organisation, but I can’t because CNAME can only have the same target once.
So, is there a way I could allow multiple custom subdomains using CNAME (I.e. using a wildcard) and what would be the required steps for it (Including any security stuff needed to avoid abuse)?

Also, to be clear: I’m currently not able to add A-Records for GitHub Pages which from what I know could allow multiple subdomains, due to the domain being used on other places too.
