Oracle Project Management - Project Resource Event

I am trying to better understand how we can display Events and their total hours from Manage Resource screen without any OTBI reports. At this point it only shows duration per day, event when the event are multi days.

How can we make it to show that instead of duration per day, it shows the total duration (in hours) based on the start/ end date of the events and calculate it? It is missing the total hours for Events.
