Property of the ScriptLine: Inserts.
This option, which is closely linked to the property insert first page, lets you decide if the ScriptLines that are to be inserted at every occurrence of an Insert ScriptLine should be inserted before or after the page where the date occured.
By default, pages will be inserted, starting on a left page. If you prefer the inserted pages to start on the right (to insert a re-order sheet on October 1st, as shown below) :
Insert before (start on right page)
Insert after (start on right page)
then use the property insert first page.
