Hey there!

- If you want to add all sub-domains from a specific domain to be under the same group, there is an option under the "Advanced" section of "Group by sub-domain". You can turn it off to achieve that. For example, for docs.google.com", and "mail.google.com", you would see them *both* under 1 group named "google", instead of 2 different groups of "docs.google", and "mail.google".

- If you want custom mapping that you yourself can set, I'll make sure to prioritize it in my list of planned features!
