Hi Aniruddha,
First Solution: if all windows other than main window is same in all pages, you should use 14 folder in main window and command node after each folder to trigger page break. Inside each folder you can add contents which you want to print in particular page. If you don't want to print any page you can use condition tab of folder
Second Solution: In command node you can maintain new page. In your case you have 14 pages, then add 13 command node in each page and put condition on each command node. Based on your condition only one command node will execute and page given in this node will be your next page.
