Suggestion - Add wildcard to email spam filters

I receive a LOT of spam emails, and MANY of these come for domains .icu and .us. It would be MUCH, MUCH easier if I were able to add a custom filter like From contains @*.icu or @*.us. This does not seem to work, so I am forced to include the full domain name, which results in LOTS and LOTS of custom filters. Could you PLEASE allow for wildcards in custom filters? That ability would be so very helpful.
