Ability to use sprints when backlog not sorted by rank

Original summary Ability to use right-click "Add to Sprint" for issues in a backlog sorted by something other than rank

Although it is currently possible to change the filter on a rapid board to show the backlog sorted by something other than "Rank", doing so completely locks the backlog so that you can't change the order OR move backlog issues into the current sprint.

I understand completely why the backlog ranking is locked in this case and am not asking you to change this behaviour.

What I do want is to be able to Right-Click on an issue in the backlog and "Send to Current Sprint".when the board is sorted by anything other than rank.

This would allow me to view and assign issues to the sprint during sprint planning while using a view that is based on my idea of priority (i.e. business value), but would not require any changes to the default rank mechanic.

This simple change would save me hours! Dragging and dropping issues to sort them in a list of several hundred items is just not workable.
