How do I move my wishlist into the Shopping assistant?

Thanks!

There isn't a 1 button way, but this will do the trick:
1) Go to your wishlist page
2) In the upper-right select View > Text Card List.
3) Copy everything.
4) Go to the Shopping Assistant.
5) Select Add Card From List.
6) Paste the list.

Let me know if you have any questions!
