Can multiple people add items to the same wishlist (collaborative list)?

Currently, each person creates their own list. However, you can combine them: Have one person create the "master list" and send it. The other person adds their items on their device, generates a second link, and you merge them manually by looking at both links.

Or, sit together at one computer and build it together! Not ideal, but works for now. Maybe a feature request for the future?
