Here's the status right now:
Currently I can get the Universal Items from a wishlist.
Of course there is a "problem"
Unlike an Amazon item which has several image size associated with the ASIN, A Universal Items seem to have only one picture associated with it. This picture has no info on how big it is, so showing a picture from a Universal List could mean a giant picture compared to the Amazon items.
I'm debating showing the No Image picture for Universal items
