In the project or contract list, office-specific and comprehensible lists and evaluations can be defined and saved, which also allow evaluations of office-specific project groups.

In order to be able to better understand the columns (planning totals, cost totals) that can be selected/displayed there, for example, and to be able to drill down there as well.

Since the fields (result according to payment status, result incl. planning, project liquidity from today) but often involves totals, it would of course be necessary to clarify what you expect from a drill down.

Here are two examples:

Result by payment status

Here, costs in annual slices could be compared with income in annual slices. This would give you a quick overview of the progress of the project. A further drill down would then perhaps lead to the upcoming new controlling.

Project liquidity

Here, as before, the planned expenditure (possibly with the planned full-time equivalent) would be compared with the expected income in annual or Monday slices (perhaps depending on the duration of the project).

Etc, etc

It's a wide field, I know.

But I think that it would be a consistent development of the drill-down concept and would provide a faster overview and insight into the figures presented.
