Help Needed to Modify Script for Inserting Two Layers of Particles with Different Compositions

I'm currently working on a particle packing simulation where I'm using a script to insert particles and simulate pressing. I want to extend this script to insert a second layer of particles on top of the first, with a different composition ratio of the same two particle types. After both layers are inserted, I would like to proceed with the pressing simulation. I have managed to insert the first layer successfully, but I need help modifying the script to add a second layer with a distinct composition.

I will provide you with some snippets of my script for simplification:

# Initial Setup and Variables
atom_style granular
atom_modify map array
boundary p p f
newton off
communicate single vel yes
units micro

variable alphastart equal 0.4
variable xmin equal -29
variable xmax equal 29
variable ymin equal -29
variable ymax equal 29
variable zmin equal 0
variable zmax equal 58
variable atomTypes equal 2
variable rad1_1 equal 0.5
variable rad2_1 equal 2.5
variable ratio1_1 equal 0.11361
variable ratio2_1 equal 0.88639

..........

So, how to script the insertion of a second layer with a different ratio between Type 1 and Type 2. the second layer should basically occupy the rest (60%) of the simulaiton box (40% is initial layer).

I would be very thankful for every assistance. Thanks in advance
