Finding Text instances that override main component?

There’s an issue with text instances that originally got their content from main component but have “gained independence” due to overrides. How to find and reset them?

Scenario1: some text instances have been changed because it made sense at that moment. However, the main component changes in a way that all it’s “children” need to be reset.

Scenario2: I found a few texts that needed to be changed everywhere. Rookie as I am, I did search and replace over all pages. Some of the texts were linked to main, as it turns out, and now I need to find them and remove override.

Any good plugins or methods? There are many screens, so I’d hate to do it manually.
