Changing the maximum character count and time in the text editor for notes. Is it possible?

A friend of mine wants to use notes, to make an ingame diary.
After multiple hours of trying to figure out where I could possibly change the values for the maximum character count, I came to the conclusion, to ask this forum for help.

Now my question is:
How can I change the maximum character count and time until the text editor closes?

I couldn’t find any of these values in the ARK Dev Kit. Maybe they are in some file I just haven’t looked at yet.
Really hoping someone can help me with this.
Even a simple “Just not possible right now” would be nice.

-Thanks in advance!
