Mitch, welcome.
Not sure what you your problem with tiling is. Is it the tiling itself or the sizing that is a problemR
Tiling was was done for convenience mostly. And cost as well. Typically most of us do not have access to the large capacity printing. Sure its better to have a plan on a single sheet. In that respect you have a definite advantage.
If it is the resizing that is your real problem then the solution is TilePrint.

I think I am the only one to ever ask about putting tiles together before now.
