Tagging users

Possibility to tag a user in order to cluster users and have an aggregated view by category, also in relation to a specific time period (1 day / 7 days / 1 month). From the user profile, I can assign them a category that will be saved, and in this way, I imagine being able to select the category (i.e., the reference tag) from a filter in the dashboard and get an aggregated view of the events only for that category (e.g. consultants mostly sign in person, mostly use PDF, etc.).
