Hello, I am trying to integrate Trello into my company as a sort of tracker dashboard for sales deals that we have as a way to have each member of our team see where each project is currently in our process. The administration team needs to see each and every card, however the sales people themselves need to see only their cards, not the deals of other sales people. Is there a way to have it all on one board where say 6 people can see every card, but each sales person can only see their cards? I know you can change edit permissions but is there a way to change view permissions on a card by card basis?
