We have fix sprint dates and would like to have those sprint dates defined at the beginning of a Program Increment (PI). Once the PI planning session is over, the team would add relevant user stories to the correct sprint. It appears one cannot associate sprint dates until the sprint is started (and can't start unless there is at least one issue belonging to that sprint).
Question: Is there any potential "damage" by artificially starting all the sprint so that dates are visible and the teams can upload the stories to the right sprint? Is there any reporting impact? Is the best practice to only start the sprint whenever that start date hits?
Thank you!
