Row insertion
You can insert a row before a section or a field. This provides an easy way to insert fields/tabs into the middle of an existing layout. Begin by selecting the section or field in the Navigation panel. While the section or field is selected, there is an action labeled Insert Row at the top of the Form Wizard's Layout tab.
When you select a section and click the Insert Row action, the system increments the Start Row property on all sections in the tab from that section on and refreshes the selection.
When you select a field and click the Insert Row action, the system increments the Start Row property on all fields in the section from that field on and refreshes the selection.
