lightning to sd card iphone import settings

Dear Community,

I'm a photographer and I'm using the lightning to sd card to import photos live to my iPhone 6s Plus 128gb. The problem is that when I've shot a lot of images (say 1000+) the thumbnails load really slow and start to render with the first images I've shot. If it's possible to let the thumbnails load the last images first it would be a lot faster for me so is this an option?
Or does someone have a better idea to send the last shot images to my iPhone quicker than this?
