Anyway, here’s a workaround (although I don’t know if it satisfies your needs):
In Model Explorer | Workspaces | select particular WS | see the Entity Shortcuts, Relationship Shortcuts and View Shortcuts folders.
If you want to edit entities by WS, you can edit them right from this place - one entity (relationship, view) after another.
Note: When you double-click the item from this place (under the Workspaces item), the object will be highlighted on the particular WS.
When you double-click the particular entity under the Entities item in ME, you open the Entity Properties form.
… So, this was just a little note…
Well, I hope it might help you a little…
Have a nice day.
