How to increment the names of images

[sch.mnk]

I have not yet figured out, even after much searching, how to increment the names of images by 'add multiple images'. Is that even possible?

If my photos are named e.g. CIMG1638.JPG, CIMG1726.JPG a.s.o., but in the gallery should be named "Summer 01", "Summer 02", "Summer 03", etc.
Is it possible by 'add multiple images' to enter the name 'Summer', with the option to add incremental numbers? If so, how?

Is it also possible to rename multiple images at once?

Hi, such feature needs to be customized. The titles are automatically taken from the filename.
