Hi,
I've never tried myself, but I would not be surprised if you could do something of that kind with GROUP in LAYER object. Excerpt from mapfile reference http://mapserver.gis.umn.edu/docs/reference/mapfile/layer follows.
GROUP [name]
Name of a group that this layer belongs to. The group name can then be reference as a regular layer name in the template files, allowing to do things like turning on and off a group of layers at once.
