New Feature Request for Board Permissions

Would like to submit a new feature request to enhance the permissions on boards to go farther then what is currently there. Right now we have boards where we would like to be able to control who can create new items within the board, but still want them to be able to edit information within the items that have been created, but there is no permission to do this at this point unless you use a person column, which we have multiple people that “own” the information within that item in the board so this is not possible for us. Would be great to get more security/permissions available for the boards.
