Group Legend question: How do I have a group show up on the legend, but not colour my members?

So, I would *like* to have a group on my Legend, but I don't want it to colour the members who are in said group. But every time I un-check the "Colour Group Members" the group disappears from the list.

Is there any way to keep it on the list (it's an important group, so I wanted it near the top of the list) without it colouring my members?

Thanks for your help.

I don't think it's possible.

You could just have the colour as the same colour as normal members without any groups. But then when you go over their name, there will not be a highlight colour.
