Maybe I'm missing it, but I did a search for "Match Properties" in this forum and most of what came up involved hatches, sketching, drawings, etc. I dont see any posts that reference parts or assemblies and the "matchprop" command.
This is what I mean; I just made a plate of 3/16" stainless steel to be used as a walking surface in a dairy plant. The outside edges are broke up 90 degrees to incorporate the necessary kickplate. There is technically no diamond tread plate in the sheet metal environment, so I just ctr-LMB all the surfaces that I want to have the diamond plate appearance and modify the properties to diamond plate. It can get a bit tedious to make sure I clicked on all the appropriate surfaces day-in and day-out. This is where a "matchprop" command would be useful. Select the source surface appearance, then select all the subsequent surfaces you would like to exhibit that appearance. Take that a bit further into assemblies. We often help each other with projects and one person uses "expanded metal 01" and the next guy uses a different expanded metal appearance. It would be nice to "matchprop" them to appear the same too. Just sayin...
