task/resource overview per main task

[Quasar]

Hello, i have alot of maintasks subdivided into subtasks. I have a
couple of resources allocated to those subtasks. every resource has
limited time (20%) and different costs per resource. What i want is an
overview, or report or whatever that gives me for every maintask the
hours and costs per resource. So the subtasks are aggregated.

Example main task is Design Fase, subtasks can be
projectmanagement;meeting;Design proces; etc. every subproces has its
resources allocated. I want to see this:

Design fase
- resource1 60 hours 1000 euro
- resource2 45 hours 800 euro
etc

(so you wont see the subtasks)

I just cant get this to work

help plz

thanks
