When looking at the Plan view of a scrum RapidBoard, is it possible to add issues directly to a sprint? There is a link against the Epics for adding directly to an Epic.
You may enter the Sprint Id the in the 'Sprint' field while creating the ticket -> (this is kind of pain as you need to know the id of the Sprint and not the name)
[Update] - You cannot create a ticket directly in the current Sprint (at least the way my JIRA is configured) except by adding the Sprint Id. When I had one of the tickets in the current Sprint selected, and I created a new ticket, it does however place the newly created ticket at the top of the backlog. At least, this makes it easier to just pull in the current Sprint
