As the title mentions it will be useful to have the option to book a number of hour per week and not per day.
- "Resource 1" booked on "Project 1" for 20 hours on "Week 1"
- "Resource 1" booked on "Project 2" for 20 hours on "Week 1"
This will have an overview of the resources allocated on different project on a week bases and not per day.
So in the end the employee can manage himself how many hours he dedicates per day on the project that he is booked in that week.
The manager doesn't need to administer at a micro level the employee's time and he can calculate and allocate easily the time per week.
