Multiple design layers in the same setup

I am trying to figure out how to add multiple design layers in the same product configuration. 

I am using the Multistep product configurator with fancy product designer. 

Basically what I am trying to achieve:

Step 1: select a basic design (from the fancy product designer category "base design")

step 2: add some text and color

step 3: Add another design on top of the current one (also from the fancy product designer category "top image"). 

It seems that I cannot add two layers after each other while still having control over it's contents
Both step 1 and step 3 are design steps. 

I included an example in the attachment.

1. Is this possible?

2. If yes, how?
