Feature Request: Find-replace words in sentences

[HandOfCthulhu]

When generating audio, the user may find on review that certain words are consistently mispronounced by the TTS engine, and may want to replace all instances of that word in all sentences with a phonetic spelling. The operator should be permitted to do that within the application, and have every sentence containing that word be marked as needing regeneration.
Example: The name "Dana" gets mispronounced by F5TTS as "Danna" requiring the user to rename them as "Dayna" throughout the text, and want to regenerate the sentences required to fix this.
