You need to do calculations or averages in the list or table view when using rollups!

For example, if I want to see how much a customer has been billed to their folder and, on the other hand, there is the FINANCE space, the same task must be DUPLICATED in the CUSTOMER's folder to perform the calculation.

Even in the panoramic view, it would be important to see with the naked eye, in addition to the tasks you have pending, such as your performance and financial status. That's critical to evaluating the quality of that customer.
