Adding slide sets
A Slide set is added to your plan time-line by selecting the check box associated with those slide sets you wish to add to the plan and then selecting the Add selected to Plan button.
Ordering of slide sets
You can change the order that the slide sets appear in the plan by hovering over the slide set number in the time-line to the left, holding down the left mouse button and drag the slide set into a new position and then releasing the mouse button. The slide set will then be renumbered and slotted into the desired order.
