Structure / Categorization of Reports

We are using Power BI in our company and want to add all reports we are creating in the whole company into Power BI (which means we will have more than 100 reports in Power BI).

For this reason we will need to add hierachies to categorize all reports. For us it would be very helpful to create the possibility to add differend categories through the app interface - I imagine to have 6 oder 7 buttons in the app interface, that lead to the reports of each category so that we can organize and structure the reports in the same way for all of our employees.
