How to make the background of LibreOffice Draw be a infinite white board instead of a A4 paper?

[marvic]

The default page setting of LibreOffice Draw is A4 paper. However there is no need for printing. And the limitation of A4 paper is really disturbing. Is there any configuration method which can make the background of Draw become infinite white?

Thanks for answering!
