Turn off outline resizing

When I create something with an outline, the outline will increase or decrease in thickness as I resize the image. So if I have something at say 10" X 10" at 4pt outline, when I resize it to 2" X 2" the outline is like 5X thicker and messes everything up.

Is there a way to combine or something with a vector so the outline auto changes or never changes thickness when resizing the graphic?

Thank you!
