Tracking Time Spent on Tags

Hey all, not new to Toggl, but new to the Tag feature. Using a free account so that I can demonstrate Toggl to the team (about 20 people).

I want to be able to track how time is spent in 4 different categories. It seems intuitive to assign these categories as Tags, since time spent on a project could be applicable to one or more of these tags.

At the end of the week, or month, I’d like to generate a report showing how much time was spent on each tag. But I can’t seem to find a combination in the Report function that displays this information.

Is this possible, or am I using Tags wrong?
