I want to create two matrix reports showing me how my team spend their time (the worklogs they create).

First I would like to see the time categorized by "Category", no matter if it was a request, problem, change or project (I know projects doesn't have categories, which they should, but let's leave it blank in that case).

Then I would like another report where the time is categorized by Problems, Changes, Incident requests, Service requests, and Projects.

I would like the reports to only include work logs that ended in the last 7 days.

How do I do this?
