Prevent cPanel Users from Creating Domain Which Have An Ignored Specific Pattern Pattern

Hello,
As I know, cPanel have a feature "Prevent cPanel Users from Creating Certain Domains"
for example, to deny cPanel users the ability to park a well-known domain (such as google.com) on top of a domain: https://docs.cpanel.net/knowledge-base/security/how-to-prevent-cpanel-users-from-creating-certain-domains/?_ga=2.238227656.911759896.1683598519-1525851306.1662517768
Beside that feature, we hope other feature which prevent user from creating subdomain which including a specific pattern. For example, prevent user from creating any subdomain with 'blackword' then any subdomain have 'blackword' will be ignore: blackword.domain.com, blackword.{userdomain}.{tld} ..
Thank you
