Privacy zones squares and rectangles useless

I find the fact that you can only have two privacy zones and that you can only block out zones in either squares or rectangles doesn’t work. If I block out the garden next to me it blocks out half of my garden because I need a triangle to block their garden,path and gate out. Would be better with a grid to fit any shape. Bit pointless having a camera that can’t see my path without also seeing my neighbours.
