Canvas sizing

Hello,

Given that the Adobe Creative Cloud is used heavily by the print community/graphic designers, I am struggling with output sizes on my canvas'. As expected we utilize bleed to facility full color prints. In doing so, we set our canvas' up either at the bleed size (photoshop) or with bleed (illustrator/indesign) to be exported with. For example, a flyer with bleed is 8.625"x11.125" for a final product at 8.5"x11". However, when we input that size, while it is capable of inputing to the thousandth, it save at the hundredth affect our bleed/trim lines. Is there a way I can setup the canvas output to save to the thousandths?
