To create a logic step, select Logic as the type, provide a name for the step, and click Ok. No other settings are needed. Once created, the logic step will appear below its parent, and the overall tree structure will re-position accordingly. A small warning icon will appear in the bottom left of the step. This is an alert for empty logic. Any step with empty logic will fail, so the alert is your cue to add logic.

These options are presented when the [Delete] link is clicked for a step.

Please note: if you delete a Logic step containing more than one branch, the branches cannot be shifted up because they would collide. If you wish to keep the branches, move them to different steps before deleting the Logic, and then move them back in the desired order.
