Yes you can. The “levels” are just a logical abstraction that can be used to create:

• vertical logical partitions of a building made by multiple floors.
• logical partitions of different areas (even far away each other).
• logical partitions of different areas belonging to different customers. If you are a system integrator working with multiple customers you can create multiple levels for each one of your customers or we can create a new site for each one of your customers.
