Indesign margins

[irishgrizzly]

I'm setting up a long document in InDesign. I need to have facing pages but different values on the left/right page margins (see pic). I need something like;
right page: Inside 30mm Outside 10mm
left page: Inside 10mm Outside 30mm

Is this possible, would this be something I'd need to set in two master pages?

Thanks,

I think I got what you are looking to do working by setting my margins without having facing pages, and then going back in after the document was setup and clicking the facing pages button. See if that works for you.
