How to whitelist domains using Screen Time?

I would like to know how to use the "Allowed Websites Only" feature, in the "Screen Time" section, in "System Preferences", to allow access to specific domains only.

1. Would it be possible to use wildcards to allow subdomains? Eg: *.google.com, *.wikipedia.org
2. Would it be possible to allow access to the domain, and its sub-requests initiated when loading the website? Currently there are too many popups that request permission to allow sub-requests. Eg: Some sites, store CSS or JavaScript files in CDNs and the requests are blocked
3. I would like to know if Apple has a feature request page?

Thank you!
