Hi Will,
Yes the steps of the Customizer are changeable and orderable on our end, we can remove step 1, moving the other steps up in order, or change the order, or put in custom steps.

1) Add Image
2) Add Text
3) Save
We can make a custom UI setup for you with a custom development package. You will want to speak with Miguel to get a package set up. You can also use our Get a Quote page to do that, which is located here:
