warped object in Adobe Animate

I mean that I run "copy frames" command in one document on the layer with animation which made by using warped object, and then, run command "paste frames" on the blank keyframe in timeline of another document - I have to choice to replace object (warped object) or don't replace - if I dont replace it - I have to lost my animation ( but miraculously warped object is copied at the first keyframe, allthough at the second and folowing keyframes - don't). This is sence why I want to rename the instance name of warped object in hope this will help me.

bottomline: you can't and it's irrelevant (because you can't reference it in code).

but you convert it to, for example, a movieclip and assign it an instance name.  (but the object on the movieclip's timeline will still have the default instance name.)
