Why SO many random DCIM Folders? I want ONE!

I have an ipone 4s. I have had an iPhone for over 5 years now. Before the DCIM folder would hold 1000 pictures. As soon as I would take another picture (ei 1001) then it would start another folder for those thousand pictures. So by time I got into the 5000+ I had over 5 folders. They are random (ei 851PKYZB, 851XTGOR, 914ELZYG, etc.) Last month or so when I plugged my phone into the computer to copy my photos onto my desktop I had ONE folder. It was glorious not to have to open every folder to figure out where the newest pictures were.

Then today I plug my phone into my computer to copy pictures over and I now have a folder for every 100 pictures. YES TONS and TONS of folders (55 folders to be exact) and no rhythm or reason to the numbering system. Some with only 1 picture in them, as I delete a lot of pictures after transferring to my computer. So when I wanted to find todays pictures I had to open over half of them to find my pictures.

HOW do I get it back to ONE folder? I understand the reason there is a DCIM folder to begin with, but I really think I should be able to have 1 folder or at least have them numbered 100APPLE, 101APPLE, or something that is numeric and I know that the very last folder are the new pictures. Any ideas or suggestions would be greatly appreciated. (I have the newest iOS 8.1.2) Thanks in advance.
