Making amounts visible in grouped statements

As a user, in the grouped statements I want to be able to see the individual amounts and the total amount per group so that I can quickly understand the financial breakdown per customer, project or other grouping.

Explanation:

In the regular (non-grouped) view, I can see amounts per record, but as soon as I group the data (for example, per customer, project or employee), these detailed amounts disappear from view.

By making the amounts per registration as well as the total per group visible in the grouped view, I can make comparisons between customers or projects in one overview much more efficiently, without applying extra steps or filters.
