deadzones for trackpad

I would love to have an option where the touchpad does not detect my finger at the very bottom. I am someone who uses his right hand to scroll and the left hand to click. I often rest my finger directly at the bottom left corner of the trackpad. I want to be able to have this finger sit on the trackpad but not mess with gestures or scrolling, but still have it be able to push down for a click. would something like this be possable
