One perimeter for all top and bottom layers

[sssvolk]

My desire is simple, and I assume that other users also want the same.
There are many products that, even with a rectangular shape, want to be aesthetically beautiful. The type of product with uniform filling of the upper planes looks more uniform than products with planes with a wide perimeter!

I ask you to:
Add a function to select ONE perimeter for the bottom and all top layers.

Explanation: ALL top layers are the surfaces of the printing steps.
