Parent/Child Reports

I’d like to be able to update a single ‘parent’ report and have the changes in structure/filters to be reflected in ‘child’ reports on various dashboards.
For example, update the displayed properties in a ‘parent’ report on the forecast revenue for the org globally, and have regional/national ‘child’ reports pull through forecasts for their subregion only.

Yes, I totally agree. More needs to be done with the parent/child feature.
