I would be nice to be able to share the same record in different vaults. For example, I want to share an item with a vault created specifically for my sister, and I also want to share this same item in a vault that I share with a friend. When I edit an existing record and place it in the vault for my friend - it is automatically removed from the vault created for sharing with my sister. So it would be nice to be able to place a particular record to be accessible in more than one vault.
Thank you for the request! This is something I could tell would be requested at some point, but it is going to be a bit of a process to get it implemented. I'll get it written up for the development team, and we'll talk about it more as we discuss features to add in the future.
