Trackpad gestures: swipe in top half/bottom half

I would like to be able to create different actions for trackpad swipes depending on where on the trackpad I start the gesture. The Magic Trackpad 2 is large enough that I feel like it could be subdivided in two or even three rows.

Currently I use five finger swipe left or right to move windows left or right. Ideally I would be able to do a top swipe to send a window to the top left, or a bottom swipe to send the window to the bottom left, or a middle swipe to send the window to fill the left half of the screen.
