Is there an efficient way to rename and re-screenshot all my saves?

[NameTaken55]

Most of my saves are named something like
1213131212222121
or
wasdsawaswawaes
It makes me cringe looking at the mess ive made and id like to organize it, is there an addon or just an overall more efficient way to do this?
Thanks to all the helpful replies, in advance.

Just open the folder in explorer and ctrl+scroll the icons big enough that you can see the screenshots. Then for each save, you can select both the .bls and .png and rename them together.
