On my entity I have some auditing fields like ModifiedBy and CreatedBy. When you generate a screen by dragging the entity on the MainFlow you don't want to have these fields such as ModifiedBy and CreatedBy generated as fields on the screen. Just like the Id attribute is not generated on the screen.
It would be nice to have an option when declaring an entity attribute not having this field generate on the screen. For example if you have an audit field like ModifiedBy or CreatedOn.
