Change the duplicate token input behaviour

When duplicating a token, it would be very helpful if only the -copy or even better, the last string after the last . would be highlighted—this way, I can instantly start writing and give the token a new name while it is still placed in the same object group.

the current behaviour is that the whole token path gets automatically highlighted, requiring me to use multiple combinations and/or clicks just to remove the -copy and often the name before that, just to start writing from the dot again
