JIRA Portfolio can import and use story points on each story ticket for Scrum Teams, but for Kanban teams can JIRA Portfolio base the duration of time for each ticket from the team's cycle time in JIRA Software? If not, how does JIRA Portfolio set the duration for each ticket, as part of a continuous flow? Can T-Shirt sizes on each ticket in JIRA Software be imported into JIRA Portfolio and configured with a set duration of time, for the estimate?
