Dear Pankaj,
Go to pages dimension and click on the arrow button next to it as shown below.

Now manually drop the pages one by one. It is FIFO basis and first page you have dragged will be at the top.

If there are less numbers of pages, it will be fine. For more line items, it is be more manual.
Thank You
