If you want to move a wish to another wishlist or copy it so it also appears on another list, start by finding the wish you want to manage. Click the three black dots next to the wish and select “Move to another wishlist”.
After clicking “Move to another wishlist”, you can move the wish by clicking the plus sign (+) next to the wishlist you want to move it to.
If you want to copy the wish instead, you’ll find the text “Copy to another wishlist” at the bottom of the same window. Click it and select the wishlist you want to copy the wish to.
