Override Diff View
The Override Diff View shows a detailed list of all the Template Overrides for a Template Instance. In here you can compare the overridden value to the value in the Template Asset and you can select which overrides to apply or revert.
Click on the dot next to each override to see a dropdown menu to apply the override. If you have nested Templates then you will have the option to apply the change to any parent Template.
Click on the dot next to each overrides and click Revert to revert the override.
