I have compiled open-source PyMOL v2.2.0a0 under Linux OS.
Reading this webpage and seeing this video, I tried the "copy to object / new" command on selections, moving them indipendently with the mouse in "edit mode", saving the state of the scene after each edit, but I can't interpolate between them.

best regards

There is a working example:
You can save it in a .pml file (eg script.pml), in the default PyMOL path, to be able to call it with the command
