Hi there,
the best way to create full width Hero elements is to:
1. Set the Page Builder Container to Full Width.
2. Use the GenerateBlocks Plugin to add Container Blocks:

With this method you would divide your page into Containers where you can choose to make them Full width or contained.
In GPP 1.11 we will be introducing a new element which will allow you to automate Hero elements using the block editor. We hoping to reach Alpha release very soon.
