Route notification emails

Hello,

we'd like to control which email notifications about new questions are being sent to which Q&A-admin (routing goes by category (parent+sub)), simply to map the corresponding responsibilities as a moderator.

ie. somebody is posting a new question in cat #1, then a certain user (OR user group) is sent the notification to confirm this question.
Other categories are maintained by other moderators, if chosen in backend.

Is this possible to realize without a big hassle?

Since we need this feature rather soon, can u give some advice how and where to add/change the code in order to achieve this, if you don't plan to do this anytime soon.

Thanks for watching!
