It sounds like you're looking for something quick and dirty, so this
probably isn't the type of solution you're after, but you could use
switch nodes in your render tree and create expressions to parameters on
an implicit cube, then override the parameters on the cube to control
the switching on all the materials.
I've also sometimes been able to "trick" the materials on clusters into
using overrides by putting the material on another object, then putting
the object in a partition and overriding parameters of the shader.
I.e., don't just apply a shader to the partition -- override the surface
color or whatever. I don't think that'll be totally reliable, though,
if it even works. This technique has definitely worked against me in
the past, where I wanted two objects with the same material to get
different overrides -- they seem to just choose one instead.
