Pick the one that you want to 'clone'. (and only that one, do not create a picklist containing more sprites)
Store its expression Sprite.AsJSON in a local text variable.
Create object somewhere outside screen or so, does not matter.
Use the action .... Sprite > Set from JSON ... to set the Just Created sprite to the local variable.
The 'clone' should now be exact.
Meaning, now you have to set its positions and other things that that you want to be different.
