Final answer:
Template Mode allows you to add a new markup with identical visual attributes.
Step-by-step explanation:
The tool set mode that will allow you to add a new markup with identical visual attributes, shapes, and size as that of the saved markup is Template Mode.
Template Mode allows you to create a template of a markup that can be applied multiple times with the same set of visual attributes. This is useful when you have a particular markup design that you want to use repeatedly without having to manually set the attributes each time.
For example, if you want to add a specific shape with certain visual attributes multiple times, you can create a template in Template Mode and then apply it whenever needed, saving time and ensuring consistency.
