Just what I was looking for. Thanks!

In case anyone else is viewing this question, the above suggestion to search for the Undo term does work, if the term is entered correctly; in this case, it shouldn’t contain a colon.

If the action was called “Shape”, then the undo term would be “Undo Shape” (not “Undo: Shape”).

Hi all. Does anyone know if it’s possible to apply a single texture (e.g. a custom texture map layer) across all the particles in a replicated set? I don’t mean that each particle has the whole texture map, rather that the map covers the whole set once. Thanks in advance!
