How to make alias "domain.tld > subdomain.anotherdomain.tld"?

PLEASE, reply you who make this really work.

I know, that there should be two ways, but they do not work:
1) In Plesk there is no possibility, because you cannot work with subdomains as with domains, you cannot select subdomain and set aliases. Better said, I do not see that option.

2) Second, ServerAlias in vhost.conf files of subdomains are ignored, so this do not work too.

cPanel has this, and I am on the crossroad, where I choose between Plesk and cPanel. I have 28 domains on one server and have to decide, which panel to buy. I used Plesk for years, but pay for help is bad for me, and forum is just a forum, not helpdesk...

I see one solution, but it is workaround...
Creating subdomain not as a subdomain, but as a domain. For example, I have to create new domain called "subdomain.anotherdomain.tld". Then I have possibility to add some aliases to subdomain.anotherdomain.tld, and that works.
