Ability to report ideas by parent category

We need ability to show idea data based on high-level category. (ref attached picture)

Every week I provide exec summaries to our product leadership who are only interested in data around the product at a high-level view.

To accomplish this, I have to either:

A.) Create a report for each filtered view which is unsustainable as sub categories change (aha doesn't allow for category auto-updates like products under a product line). Additionally, I cannot manage 15 reports just for a single roll up view to then paste all 15 reports to a presentation slide to make it look like something most easily accomplished in other applications.

B.) Use a 3rd party tool such as PowerBI, Tableau, Smartsheet, Excel that can create a true parent<>child relationship for categories. Aha would then only be used as a data repo.
