Material Presets for Groups

in The Commons
Can I create a global material preset for a group of items? Say I have grouped dishes in multiple stacks and I need a one-click solution to change the color or shader setting for all. The first in each stack is a unique object, the rest in each stack are instances.
I've tried selecting the objects then doing a material setting to save, but when I reload the set, select the same objects, and apply the new material setting it doesn't work.

Instances all have the same materials so I would assume that a preset applied to the main item should apply to all.
If they are all instances of the same prop, they will follow the original. If there are several different props (with or without instances), save as a hierarchical material preset. A good practice would be to create a new group node and add the props and/or figures then save the hierarchical material preset with just the group node selected. To apply it later, select the group node (not the items in the group).
ditto what NorthOf45 suggests.
i always group related scene objects. but i didn't discover hierarchal material presets until this month. it's a great trick, and a huge timesaver. :)
