You could add a method to both interfaces, like isCheckboxDefined(), and let the script decide upon that.
Another solution would be a more polymorphic approach. Let the script delegate to the interface the custom behavior, and let each interface (or the .as it extends) know what to do. Another solution would be to use one interface instead of two, and disable the checkbox for one of them.
