How to group by multiple columns in a report definition

We are using 8.6.1. In report definition, we can only drop one aggregate column and one group by column in chart. Could we group by multiple columns? Thank you.

@SamW0799 - you can use stacked charts to visualize more than one dimension. Here is an example. My report groups displays cases per facility (bars) and status (stacks). There is one aggregate column in the report definition (a count of pyID) and the two columns Facility and pyStatusWork.

If you need more dimensions, I suggest using drilldowns (on the report viewer tab of your Report Definition).
