Here is how you can add the header master to any other screen

1. Navigate to the screen on which you would like to add a header.

2. Click Add header on top of the content panel (see image below).

Just as you can customize any screen, you can also customize the master template (see image below) – however, with a different selection of blocks. E.g., the Avatar block is unique to the header screen. Simply drag and drop your preferred building block onto the content panel as usual.
