Exclude a range of websites by domain wildcard

[klingtnet]

I use a bunch of websites where it is cumbersome to deactivate the dark mode for each subdomain.
Is it possible to exclude websites by subdomain, e.g. using a wildcard match *.mydomain.com?

custom rules/filters can be part of every global extension + By Keywords/ by Regex. / by page properties that the extension might understand already or by source code.)

• +Consensus rules (crowdsourcing / voting about every rule from developers & users)

Has this been implemented? If not Id like to attempt it (no promises.)
