It's fairly simple, as you can see in my example, while dragging the Level 2 Views into my sheet, an "ant line" (clouded in RED in the attached image) appears aligning your Level 2 view to the view beside it which is Level 1. You can also do this while aligning the View Title below the views.
For some reason, I cannot attach a GIF screen recording so I just zip it up and attached it here. Kindly download and unzip on your side to see a better example.
Hope this helps.
