Canvas Formatting - Multiple Report Pages at once

It would be great if given the ability to format the canvas settings for multiple report sections, at a time. This along with potentially allowing users to do the same with canvas background & wallpapers.

My current team has UI standardization's where I require a custom Canvas Setting 'type' --which requires me to adjust the settings for each individual report section created. We often use the same background and/or wallpapers for reports, and allowing users to adjust multiple pages at once, would be great!
