Automatically update present object types and attributes while import

While importing objects using CSV, enabling the flag Automatically create object types and attributes creates a new object type every time.

What is expected:
There should be an option to automatically update attributes of the object types that are already present.

Use case:
Suppose that in a CSV file, there are multiple Node Names present. Each Node Name has multiple Product Codes associated with it. Card Type also has multiple Shelf-slots linked to it. This way there are multiple entities dependent on each other. In the Assets schema, an object type is created for each entity. While importing data through the CSV file in the schema, it would be great if the object-type specific data is imported automatically without any manual effort.
