Re-arranging CATIA drawing sheets?

[cadddict]

How can I re-arrange CATIA drawing sheets. Lets say i make sheet1..2...3...4...5....7....9....6, now i want to move sheet number 6 after sheet 5. How can i do that ? It's the reordering of sheets that I'm referring to.

Im using Catia V5R16 SP5

Any help would be great.
Thanks.

In R16 I think you can only copy and paste and then delete the first one, so here you would move first page 7 and then 9 to finally remove the old 7 and 9. In R18 there is a reorder possibility
