Best app I've found – Giftster - wish list registry Review

This app has been great for our family but I wish it would add one feature: I would love to be able to add items to someone else's list. For example: my brother asks for a coffee maker but I know he also doesn't have a grinder and I'd like to get him both. I'd like there to be some way to indicate to this to other family members so he doesn't get a repeat gift. Some way to add an item so everyone but the recipient can see.
