Text field showing FULLTEXT in LIST page

Hello,

Is there somewhere in the project to set special variables like this: $fulltext?

In LIST page when one TEXT field is too large, it adds a "MORE..." link, that I don´t want.
I would like to show all the text.

I saw that exist one variable that do this job very well.
In the output file "ViewControlsContainer.php" in the CLASSES folder I found a variable called "$fulltext" that does exactly what I need, showing all the text content without putting the "more ..." link.
However, the default is settled to false. If I change to true manually directly in the output php file, it works very well.
But every time I build, this variable is overwritten to false.
Can anyone tell me where I can adjust this variable to true without worrying about building, over and over...?
I could not find this feature in help files.

thanks,

Marcos
