Allow to sort sprints in the timeline

Filtering or sorting by sprint (or multiple sprints) would be really useful to see which stories have been scheduled for the week. At the moment our plan goes several years ahead and the graphical schedule is so small for each story it's time consuming having to hover over to see which story is against which team member and write down each story and who it's assigned to before creating the sprint in JIRA for the week.

We're using JIRA Portfolio Cloud.
