Hey @soeren-1 and welcome to our community! 
Your feature request looks interesting! I think it’s great to have this topic available so others who have a similar setup can chime in. Maybe eventually something like this will make it into the UI. But I think you haven’t made a case yet for it being a widely useful feature.
You’re new here, so let me fill you in on some things that may not be obvious to you. Adding features takes time and resources, so typically new features are added to Discourse when one of our enterprise customers ask for it or when there is alot of demand for it, e.g. rule of three. They also often start out as plugins or components before eventually making it into our core product.
For many unique cases the Discourse API and data explorer provide quick and dirty solutions that are usually “good enough”. I recognize that’s not what you’re asking for here! But sometimes trying to solve a problem using the API or a data explorer query can help make the case for adding functionality or finding a better way to solve a particular problem.
Have you seen how data explorer queries can be made available to groups, and can have a UI to specify parameters? This is suitable for “regular users” and might work for you and your team as an interim and to help you make the case here for your new feature idea. I don’t know if there’s a suitable query already out there for you to start from - the place to start looking for that is Data & reporting.
@rgj I think you’re a regular guy, no matter what anybody else says!
