Multiple Master Pages (odd + even)

Hi,

I have document with odd and even page numbers (sequential list, so no facing pages).

I create 2 master-pages, one for odd and one for even pages (becaus of different layout).

In stead of making a list of numbers i.e. 1,3,5,7,9... etc for master-page(odd) and 2,4,6,8,10... etc. for master-page (even), I would like to define: master-page(odd) = "odd", and master-page(even) = "even".

But that's not possible.

If I define the numbers i.e. 1,3,5,7,9, InDesign checks if those pages exist (?).

My document is growing, because I add more pares of pages to it, I then need to adust each time the number-list in de master-pages (add, the page numbers of the new added pages).

Is my way the right one ?

Regards,

Jan
