Enable a specific url for each sprint to open up only that sprint expanded in Backlog mode.

If you hover over the three dots to the right of the Future Sprint you can see the SprintId showing on the Browser status bar.

It would be great if one could build a url which would open the Backlog with all sprint collapsed except the one you want expanded,

The only alternative to get an url for each sprint is to save the individual queries for each sprint to their own filterID. This opens in the query navigator however
