Project Plan PDF Export on one side?

Hello everybody,

when exporting the project plan I get a PDF containing screenshots obviously designed for A4 and the whole plan is splitted into lots of pages. Can I setup anywhere that I want a PDF in e.g. A2 format which contains the whole plan?

I then can decide whether to print it on A4 or A0 but will have the entire plan on one page ...

Thanks
FF

P.S.: the scalability in the PDF export function (100%, 75%, 50%, ....) doesn't help because the resolution of the result it so low that text is not readable.
