More dependencies than "Booked effort" as SUM on project level

I've researched the Bookings/Booked Effort features in Wrike, and unfortunately they do not seem relevant to our project processes due to the nature of effort determination, efficiency in booking, among others. 

In our type of projects it currently is not relevant with the bookings in workload by project as we're highly dependent on workload by people, as we're working on a wide variety of projects at once contributing low effort tasks every now an then in a highly dependent task order.

We use task effort to determined how much time a task is supposed to take/how long it is OK to take to complete the task from a financial and qualitative perspective.

I've looked into Blueprints in order to be able to enable Bookings in our product production templates to maintain the efficiency of using a templated task lists in stead of creating each task manually in a workload view.

However, the primary benefit of Blueprints in our specific case would be the booked effort sum on project level.
In order to accommodate several ways of using Wrike regardless of the nature of projects it could be very helpful if it was possible to have more sources to view the sum of - e.g task effort, but maybe also most of the other optional columns from the table views.
