macOS Adding a Relationship With a Button (Core Data)

[elzorro]

I'm building a Core Data application, and I want a button to add the selected object (Player) to a relationship (Team) corresponding with that button. Add, fetch, insert? Is this a bindings issue, with Argument and Target?

Thanks a ton in advance for your help,
-Dan
