Change maximum characters per line AFTER generating?

Hi there. I created subtitles using the Timeline - "Create subtitles from Audio" option.
The window that opens allows to choose a maximum number of characters.
I'd like to change this number and try it in different ways, after I'm done editing. Is there a way to control it afterward? I haven't been able to find it. Any tip would be helpful! Thanx.

Project Settings >> Subtitles and Transcription > Subtitles Setup > Max characters per line.
