The ability to set an asset field as repeatable.
Extra meta field to classify a repeated field. Potentially used to filter options when used as an asset link in another custom asset.
Examples: Multiple URL links for a corporate portal.
Multiple phone numbers classified as Work, Mobile, Home, etc
Multiple Asset links -
Setting an Asset link to a computer asset type for users.
The user might have a desktop, laptop, home computer, phone that are listed under a single asset type (which would make sense if the ability to import device from Azure or integrations is built out) and you want to associate multiple devices to the one user.
Application - This example uses a feature request to use clients as a source like an Asset Link.
There could be some situations where an application is developed by company A but purchased or supported by company B and you'd want to associate those two orgs with the Application.
