Resource Utilization Report

Resource Utilization Report

I'm trying to build a report drawing from synced Projects data that will show planned resource utilization across multiple users/projects, by summing all their planned work hours for all their tasks by month. I'm able to find fields for budget hours and users, but I can't find a field that shows the time element of the table. I've tried duration and start date, but start date only shows time in the month it starts and duration doesn't offer the necessary options.

For example:
                        Jan                  Feb                  March
User X            8                        32                  40

User Y            0                        160                  32

User Z            78                        96                  12
