Domain alias as a folder of main domain, instead of a subdomain

Hi
I would like to make my Community domain a folder instead of a subdomain.
Currently we are community.warewolf.io but for SEO purposes, we want to make it warewolf.io/community

Please advise how this can be done. In your domain aliasing section you only reference sub domains.

Google no longer crawls sub domains, they need to be indexed separately with separate sitemaps and everything. 

Thanks,
