Hi.
For example: I have a pdf file with 6 pages inside.
Now, I need to insert page numbers (even, odd):
1,2 pages - title pages 1,
3,4 pages - title page 2,
5,6 pages - title page 3.
Another words: The first two pages will have the number 1
The second two pages will have the number 2
The third two pages will have the number 3
ETC
Thanks
