We have many quick 'jobs' that are set up in a workflow. We need the card to move along the process. Within the task the subtasks are allocated to freelancers that we don't want to have access to the main task. Currently we can't do that. So we end up having to set up different cards but this makes it messy as we easily need to know how long the task has taken (without the frelancer knowing) and the freelance to get paid just on what time they have taken. We don't want them to see communications we are having with the client on different sub-tasks or the main task.
