Window Manager - 1/6 should be added as possible option

Nowadays when lot of monitors are big, like 3440x1440, 4K 3840x2160, 5120x2160 it is very required that user can put 6 windows of diffrent applications on one screen, also using shortcuts. Therefore 1/6 of window option would be great help - 6 sub-options should be available within 1/6:
left-lower, left upper, middle lower, middle upper, right lower, right upper
Please add this as it would be very great help, this would work similar to 1/4

At the present one can realize such by putting one of window as 1/3 in the middle (then it is from top to bottom), then one puts another window as 1/4 and then this 1/4 window is manually shrinked to 1/6 by dragging left or right side of 1/4 window and shrinking that.

 

This is how it might look on 3840x2160 screen
