P6 Rel 6.2.1 Resource Assignments

I am assigning several resources to the same activity with budgeted quantities, progress % and remaining hours to complete.

I then need to view each of these resource assignments using the "resource usage profile" view so I can see the bars showing the work to complete.

The problem I have is that I cannot summarise the resources by activity, the activity will be visible but with all the resources listed as the header.

I know this can be done using "assignments" but this doesn't display the bars, only hours in a spreadsheet.

I have tried to filter out the individual resources by activity but so far unsuccessful.
