Aggregation of Costs, by Role or Department

Hello, (using GP v3, win10, JRE Openjdk x64 v11.0.11)
I found that there is a rate (daily) by resource, and by the assignment I can get the total cost.
Is it possible to get the aggregation of all resources of a role (or department)? Thanks! M.

There is no “department” in GanttProject model (you can add a custom property though) and no built-in aggregations, except for by-task and by-resource. You can export data to CSV and run custom aggregations using CSV processing tools.
