Subitem feature - Varied configuration

Hi MONDAY team,
Can I suggest a useful feature would be the ability to have differently configured subitems on the same board or within the same group (don’t think it would be needed under a particular pulse). Could imagine it coming into play, for example, where a particular campaign is mapped on one board, but part of that campaign is a film shoot, another part is an eDM, another part is the recruiting and managing of a product ambassador, another part is survey, etc. This would allow for each set of tailored subitems aligned with a pulse to facilitate the execution of that activity.
