Asymmetrical Liveries

I have just had the fortune of finding a really good painting program, very basic, but thats a good thing for beginners like me. I am wanting to repaint the default boeing 737, however the textures only allow for an asymmetrical design on the first quarter or third of the fuselage, then it would seem to be copied onto the other side for the remaining portion of the body. I am wanting to do a livery for easyJet, but as their logo spans the entire length of the body, is this not going to be possible (without the logo inverted on one side) Hope that made sense, I seem to ramble alot (there I go again...and again...and agin..... etc)
