Color panel: how to detect clips belonging to a certain group?

Hi!

Talking about Color-Panel: 

In a music video I have around 400 single clips (many cuts, different cameras sceneries, light situations etc.).
So e. g. I create a color group “studio, red light, Sony 7sIII” of 30 clips doing a grading as Im doing with many groups getting matched to e. g. ““studio, red light, ARRI cam”. 
5 days later I’d like to change grading of just Sony footage in that specific scene: As in the overview those groups look similar after color correction, I m a bit lost how to identify the clips belonging just to Sony footage. (just one example)
my trick for now: clicking at the group and over exposing extremely, so I can see the white and “damaged” in the overview. But this is a horrible work around which does not really help.

So, in overview: how can I identify or/and filter clips belonging to a certain group?
