Some of our tasks are assigned to teams of individuals. Sometimes there is a lead, but even then, we need all members of the team assigned to said task, assigned to the task somehow.

Use case: We have animations that need to be made and 2 animators. They work on their own time on whatever animation they choose, and then tick it off a list. The list is large, but if there was one more level to the project tree (ie we could create a sub-project for all animations needed for this project) we might be able to utilize that and make each animation a separate task, but this does not hold true for all cases.

We tried making a folded column for it under the project's task list in Kanban view, but that failed with the following trace. It would also not be the best solution since columns are used as stages towards completion or status of the projects.
