Save/export PDF setting

[willc95995471]

Hello illustrator experts

How can I save 2-pages of A4 size(3mm bleed) artboards as 1-page A3 size PDF(no bleed) in the same file? I have a client who likes to have a print(A4) file & a screen (A3) file. I am working with 2 separated files at the same time and think it might be a way around it? Perhaps this is something I can do in InDesign? 

thank you all in advance.

I would possibly maintain two files, but use the two A4 pages as my working file and Place ​them on a separate file with an A3 artboard, so one updates with the other. Stop me if this is what you're already doing.

I am not, this is a great idea Thank you Doug.

It would be much easier using indesign. Just place two pdf file in indesign and export SPREADS
