Total price of recurring services

It would be very useful to have an indicator showing the total of all recurring service prices in the Services tab. This would include all discounts, proportional discounts based on the start or end date, etc. And the ability to select the date range: this month, next month, previous month, and custom.

Customers constantly ask us: When will I pay this month? How much will I pay next month with two additional mobile lines? Etc.
