Great app, but small quirk. why is it when I adjust my factors, it adjusts for all of my GBs? Some building I only post for 1.95 and others 1.9 and even 2.0. Is there a way to adjust my factors independently from others??? It would be great to see 1.9 for some and 2.0 for others without always having to adjust the factor slider.
