Resource booking as %, not hours!

Hi,

I'm using Bookings to book project managers' time on projects. I find having to input bookings in hours in this context absurd.

One of my most frequent booking scenario is: As a manager, I want to allocate 50% of one of my project managers' time to this project, during the whole project.

Right now I have to:

1. Open the project

2. Select the Resource view

3. Set the booking on the whole project duration

4. Open the calculator and do: duration_of_the_project_in_days *  8 * pourcentage

5. Input the allocation time in hours

I'm sure this can be shortened a loooot

Thanks!
