Default image quality control

I'm interested in an easier way to control the default quality of uploaded images. So far i've been manually editing this line in GD.php:

protected static $default_quality = 75; // I change this to 100

The problem is each time I update SS, this is overwritten. Does anyone have a more practical suggestion for this that could be saved in mysite folder or in the database?

Also - it would be really nice to have this option not only in the admin area, but to allow a radiobox to chose between imageMagick and GD (I know this is a lot more work than it sounds). For now, I'm really only interested in a practical fix for controlling this image quality outside of GD.php

Thanks for the replies - I tried this and got (on the upload tab and on attempting to flush):

I tried something different based on your idea:

[edit] I'm not sure if it's working or not now
