How to have an arbitrary page size in TechDraw?

[WobblyHand]

I have a drawing that I'd like to eventually print out life size, it is about 1.3m high. All the templates that I see are too small. How does one go about doing this? Of course, I don't have a printer that will do this, but if I create a pdf file with the correct sizing, I can (and will) tile print it. A B0 portrait size page would work. That is about 1.4m x 1m in size. Anyone know how to do this?

Don't have an answer, on how to successfully do it myself, but have received a blank page B0 template in portrait and landscape from the FreeCAD forum. Sometime I will look into this. Collected another round tuit...
