The new utilization report is nice, but extremely limited in its usefulness. Has anyone found a way with Work Order or other reports, to determine utilization based on Location and including the Work Order category?

We are an external service provider and we want to be able to view on a monthly basis what customer locations our engineers are spending the most time at and what types of work they are engaged in while they are at said customer. I’ve tried using a Work Order report and simply filtering by location and viewing total time logged, but we sometimes have work orders that are open longer than a single month.

Additionally, the Utilization report would be very useful if I could filter on Category. We log some administrative and non-service related tasks and time in the system, and I’d like to view only direct labor utilization. 

Does anyone have any insights or ideas that I might be overlooking?
