Limit length of lines to read with a filter

[CMDNatsu]

Hi!, congratulations on the project I have it nice and running in my Synology NAS with the playwright-chrome working. Recently, I'm trying to use some filters to limit the amount of text I've received each time from a job dashboard, because it's not working very fast. The idea is to remove a lot of entries from months ago that I'm not interested with, so only focus on the most newer ones without fetching the whole webpage. As I said my system takes its sweet time making the cheeking to show the diff output, so with less text to gather and compare it should work faster. I don't know exactly how to limit the reading of lines to a limit, I've checked a similar discussion #1230, but nothing has been implemented yet, so looking for help!.

If it is of relevance this is the structure of the text I fetch

And that's how it goes for to many lines.
