We often use the Create Objects From Shapes... tool to turn regular polys into plug-in objects like hardscapes, landscape areas, etc. Until recently (v2018) this would destroy curvilinear geometry, but now it doesn't. Great work.
Now what we need is the ability, somehow, to run a Un-Create Objects from Shapes to go back to the original geometry from the plug-in created. There currently is no way to do this.
You can use the Ungroup or Convert to Group commands, but this often results in way too many resulting objects. For example, a very basic hardscape, ungrouped, results in 3-4 identical shapes overlapping, which is impossible to get rid of on large projects.
Just a thought.
