Change report margins according to even or odd page number

Greetings specialist!

I have a question regarding how can i change the left and right margins of a document depending wether it's an odd or even page.

I would like to know if its possible to setup a different header and footer for odd and even pages as well.

I tried using this formula in the left margin property of the report

=IIF((Globals!PageNumber Mod 2)=0,"2,5cm","2cm")

But it doesn't allow me :(

Thank you for your time
