Being able to make groups is helpful. However, I often observe the need to create sub-groups of tags within these groups, as there can be multiple underlying relationships between tags within a group.

For particularly complex projects, I currently have to leave Dovetail and have to use other tools once I reach that stage of analysis where I'm trying to establish relationships between tags.

It would be amazing if there was a way to make a sub-group within a group in a tag board.
