Just noticed the @Kirsten posted a similar use case - much more clearly presented than my ramble - with regard to situations when hubs/users ‘share’ a supplier who doesn’t manage their own product lists - and how to address ‘first enterprise advantage’ . Her question is whether the problem can be solved by allowing for users to copy lists from such suppliers to address complicated permissions. My notifications to producers is another challenge to the same ‘shared suppliers’ situation - Private vs open products
