How to add the language suffix to subtitles

[abescalamis]

I have a library of 2000 movies, but I only want to rename the .srt to add the language suffix to the subtitles, I don't want to rename anything else, I have spanish and english subtitles and in some movies I have both.

Is that possible, if so please tell me how?

Example

2 Fast 2 Furious (2003).srt ----> 2 Fast 2 Furious (2003).es.srt

Thank you.
