Custom HTML JUnit report using Gradle

I'm trying to setup a test environment for an Android application using AndroidStudio and JUnit/JaCoCo for unit test and code coverage. I already can produce two separate HTML file for both type of tests but, while the one generated by JaCoCo is good for me, the one produced by JUnit is full of verbose content and give poor information about the single test, as you can see in the picture :

There's a way to modify this layout to generate a custom report for JUnit? In my case, for example, I would remove all those lines before the test case results and add more columns to add infos about test cases.
