Not sure if this is already included in the upcoming PI Management changes, but was a suggestion from my teams.
We are looking to be able to edit the start date of the first sprint and the end date of the last sprint. Right now, those are locked based upon the PI start date and PI end date respectively. Our overall plan is that we start the PI on Monday and the sprints go from Wednesday to Wednesday. PIs will also complete on Sundays.
This is a LOW priority as we can work within the restrictions.
