In blender 2.8 how do you make a local instance of an object in use by multiple scenes? I have created a new scene using linked copies. 



Now I need to make a few of the object single-user so there is a separate object in the original and in the new scene.

Back in 2.79 there was a button for that: 



Blender 2.8 seems to lack that button.  How do I make a single-user copy of the object?

Do not confuse the object with the object data (like mesh or curve).  The mesh panel does have the button, but I need to make the object single user and that panel is missing the necessary button.

Based on some of the comments I have concluded I am going to have to get horribly detailed, because what other people are experiencing does not match how my stock blender 2.80 behaves:

Start with the default scene:


Add a cone:


duplicate the scene


and let's change the outliner to let us see both scenes

Notice that my Object panel lacks the button that would allow me to make the object single-user.

Let's rotate the cone by 180.


Oh no!  It affected the original scene


And if we delete the object from one scene, it disappears from both scenes.  WHAT!


Undo that deletion.
Let's use the Object>Relations>Make Single User>Selected Objects .


Oh no.  Now both scenes have Cone.001 and Cone has disappeared.


How do I change my workflow to accomplish the mission of having two scenes with some objects in common , and other objects have single-user versions of objects from the original scene?
Make New Scene with Copy Settings. Go to your first scene and link all necessary object to newly created scene. Go to your new scene and now Make Single User under Object->Relations works as expected.
