It sure is possible! Numbering and Section options are available in the Pages Panel menu. These options allow you to define what page starts a section and how it should be numbered. Insert a Current Page Number marker (Type>Insert Special Character>Markers>Current Page Number) in a text frame on a page or master page (recommended), select the first page of your section, open the Numbering and Section Options dialog, and enter 200 in the Start Page Numbering at: field. Hope this helps! sequentially numbering
