Automatically recognize which mutants killed by which test cases in Pitest

I am using Pitest for mutation testing and I need lots of mutants for a project (for example 500 mutants). I need a matrix which shows which mutants that the Pitest has created, killed by which test cases. I can do it manually, but it takes a long time.

Is it possible to do it automatically? if Yes how, if no what is my choices for a solution?

Pitest supports the computation of a full mutation matrix since version 1.4.3. The feature has not been documented yet, but a brief description can be found here: https://github.com/hcoles/pitest/issues/510#issuecomment-465899299

Pitest does not generate a mutant test matrix out of the box, it stops analysing each mutant as soon as a killing test is found.

Your options are to either write a script that execute it multiple times limiting it to considering a single test on each run, or to modify the code so that it no longer stops when each mutant is killed and somehow outputs the mutants killed by each test.
