What is the desired functionality that you are missing?

As an Optimize User, I would like to be able to combine Duration with Count Reports.

As an example, I would like to see in one table the number of completed user tasks and their duration as another column.

Additionally, I would like to be able to easily see multiple durations (e.g. Total, Work, Idle Time) in one chart without having to use combined reports.

In chart visualizations, this would most probably require another Y-Axis. For this functionality, we have an existing feature request: OPT-4422 that might follow after this ticket.

Which problem are you going to solve with this functionality?

It is easier to get an overview of performance if different data points can be included within one Report compared to placing them next to each other on a Dashboard. Additionally filtering is way easier if the user can do all of it in one report instead of having to use a combined report.
