Auto-sync captions when transcript is edited

When editing the Transcript (correcting spelling, search & replacing words, etc.), I'd like an option to automatically sync those changes to already-generated captions — without having to manually locate and update each caption separately.

This becomes especially problematic in two common scenarios:

1. Late-stage corrections with multiple aspect ratios
When delivering the same edit across multiple sequences (16:9, 9:16, 1:1, etc.), finding a single spelling error or needing to replace a word means manually hunting down and correcting that caption in every sequence individually — extremely tedious at scale.

2. Regenerating captions after sequence edits
If I've made sequence edit changes that require regenerating captions, but my corrections only exist in the on-screen captions (not the transcript), regenerating wipes all of those changes — requiring all caption corrections to be redone from scratch.

Suggested implementation: a toggle or checkbox in the Transcript panel that enables auto-sync, with scope options:

• Current Sequence only
• All Sequences in project
• Don't auto-sync

This would keep captions and transcript consistent without requiring manual reconciliation after every edit — especially painful on long-form content delivered across multiple sequences and aspect ratios.
