I would like to be able to customize the "List Color/Labels" at the Space level (currently it can only be changed for the whole workspace). I want to be able to see at the Folder level overview of lists custom status/stages that would be different from other teams at my workplace. For example, rather than the standard "In progress", "At Risk", "Completed", my team would benefit by seeing the overview of all our projects by Stage, for example "Research Design", "Data Collection", "Analysis". Not all the teams within a workspace will be viewing their portfolios in the same way.
Alternatively, you could allow for a "Custom Field" option in the "Portfolio" card within the Dashboards view. Right now it is very limiting to get an overall view of all projects within a portfolio.
