Grouping parts by Section in the mixer

Is it possible to group a number of parts (instruments) together in a "section", so that the section can be controlled in the Mixer?

I frequently write for big bands, and would like to group all the saxes as into one section, the trumpets in anotehr etc. It would then be great to mute or solo the section, which toggles the mute / solo of the instruments in that section. I guess this could also be extended to volume adjustments as well.
