It's a feature that would be really nice to have.
What I do now is crop out test strips measuring 2.5" x 14.5", or 2.5" x 21.75", or 2.5" x 43.5". Then I assemble those on a 8" x 44" print. The individual strips might be from several different images, or density and color wedges from a single image. I have some actions that arrange the strips with adjustment layers clipped to each one. Uses up a lot of media, but usually gets me to a good print quickly, especially with the exposure/color wedges. One thing traded for another.
Maybe you could feed 10 inches of paper, cut it, then reload that as s 10" wide "roll." Or just cut media up into 8x11 sheets.
