One missing ChatGPT feature that would make long coding chats way better

One feature I really want is the ability to highlight a specific part of a chat and attach a note for ChatGPT.

Example: ChatGPT gives me a long set of coding instructions. While following them, I might intentionally skip one step, do one part differently, or replace something with my own solution. Right now, the only way to communicate that is to send another message like “I skipped step 7” or “I changed this part to ___,” which gets messy fast and is easy to forget.

What I want is something like this:

  • highlight part of the chat

  • click “Make note for ChatGPT”

  • type a note like:

    • “Skipped this part”

    • “Did this differently”

    • “Replaced with ___”

    • “Already completed this”

That way, the note stays attached to the exact instruction it refers to, instead of cluttering the chat with correction messages. It would be especially useful for long coding help, project planning, debugging, and step-by-step workflows.

Basically, I want a lightweight way to leave contextual feedback directly on parts of the conversation so ChatGPT can keep track of what I actually did.
