Handle degradation of new code on existing issues (e.g. complexity is getting worse)

Currently I can check “New code” issues in SonarQube for problems in new code.
But if the new code affects an existing issue and makes the issue more critical this is not visible in SonarQube via that feature.

e.g. :
Cognitive complexity rule: default: Issue is created for complexity > 15.
If the code degrades from 20 to 100 this is not visible in the “new code” part.

I think it would be nice if that information would be visible in that section; I don’t know exactly what the best solution is (create new issue? define threshold? …)
