Add an "Align to Bleed" in the Align panel/options or Snap to Bleed in View.
The align pallet is invaluable to me as I design catalogs with lots of pages with bleed that switch from left to right regularly during the process, with different backgrounds too. However, when aligning to bleed, I have to manually line up the backgrounds with the bleed line, and its a minor inconvenience not to mention leaves room for human error. Would love to be able to quickly align my backgrounds to right or left outside bleeds, and also snap my backgrounds to the bleed line to make sure it is 100 percent lined up. Sometimes it looks like it isn't.
