Quickly setting new Displayed Attributes and customisations

WOW

Thank you for such detailed reply . It was such a breeze to follow the instructions, not only did I understand

  • the prototype creation but also how properties are inherited from the container.
  • the fact you can apply prototype property from anywhere by applying the properties manually by Inspector

Question
How do I edit the property of an attribute once it’s been created? For example once we created $callers , maybe I want to edit it’s type later on?
