On the iPad, when initiating a new HDR project, there is an option if you go to Photos to select your bracketed images to click 'Select' and select all of them at once. However, that option does not appear if you go to iCloud (the little cloud image at the bottom of the import window) to select your images. I've created a folder in iCloud with raw bracketed images and use that as my source for doing HDRs, but the way it works now I have to go to iCloud and drill down to that folder to select each image separately. It would be a big productivity gain to be able to select them all ay once!
