While debugging scenarios with different values (list) for modifiers, it is not clear which values is selected and used between different combinations in a specific test iteration.

For example, a scenario with modifiers like that ...

    - name: __tier4_modifier_an
      list:
        - 0.2
        - 2
    - name: __tier4_modifier_D
      list:
        - 5
        - 10

it becomes confusing which value of __tier4_modifier_an is used with which value of __tier4_modifier_D in an iteration.

Describe the solution you'd like
It will be helpful if the parameters and modifiers used for each iteration is visualized in RViz.

Describe alternatives you've considered
It could a valid alternative to have it only printed in the terminal instead of text visualization in RViz
