Control track volume via macro knobs in group track?

[hirse]

Hi
I have grouped several audio tracks into one group. In the group track I want to control the volume of the individual tracks using an audio rack and the macro controls. I've looked also for a m4l plugin, but I couldn't find anything corresponding.
Any suggestions?
thank you

There's a M4L device called "Map8" in the "max for live essentials" pack

Oh yes, that is the plugin i needed. Thank you so much.
