Adding Info Window Inline Blocks (more info here) is made using widgets.

While in the editor, click on the "Widget" button and from the list choose the option "Panda Sales Automation - Inline Info Block"

You now have two options: 

  1. Choose a unique block by selecting it from the "Inline Info Block" selector, 
  2. Display a random block that shares the same identifier. This identifier is defined when you add a new  Inline Info Block. Use this identifier in multiple blocks if you want to have those same blocks displayed in the same store location, randomly, one at the time
