Massive extraction of subtitles

Hello everyone, I’m here to ask for support before doing EVERYTHING by hand :')
I have a series (about 1000) of MKV video files from which I need to extract the SRT files (and their related font attachments) in order to import them into other files.
I’m here to ask if there’s always a simple solution or the difficult one.
The simple one would be a configurable batch that automatically migrates the SRT files from one MKV file to another (I would rename all the files chronologically to simplify).
The difficult alternative is to extract all the SRT files and then import them one by one into the “better” files.
Can anyone help me? Thank you.
