Modify the page to show when open a document

Hi there, how can I change the first page I'll see when I open the document?
In adobe there was an option under "options" to modify that 1st default page.

I've swapped the second page (call it B) with the first page (call it A) in a document and saved.
So pages are in that order now: B; A; .... ; LAST
Now when I open that document I'll see the second page in the document (which is A).
I want to see B, the 1st page of the document.
Any suggestion? Thanks!
