Toy Box Copy/Paste

So we already know you can have multiple toy boxes, BUT can you copy toy box 1 and paste it into toy box 2? Say I spend a lot of time making toy box 1 and then decide I want to make some changes but I want to keep toy box 1 in tact. Or can I make a separate save file for the toy box instead of overwriting my previous save? Also, can I copy individual pieces to paste?

One of the videos answered this, can't remember which one.

But anyway yes you can load up a toybox and save it in a different slot meaning that you have two copies of the same toybox.
