Thread personalization (persona & memories)

Okay hear me out. You know how there’s the overall personalization for the chatbot? Like in custom instructions? There should be a way to do that for specific threads - because sometimes I want a professional response and sometimes I want a more personal response.
On the same note, there should be a way to either a) enable memories for certain threads or b) disable memories for certain threads. Because if I’m working on job applications yes I want them to remember my CV. But they don’t need to remember that information if I’m doing travel planning. Additionally, there should be an easier way to make them know what to remember. Because yes, remember my CV, remember that I did this and it’s not usually in my CV but it can be useful sometimes. But don’t remember that I’m applying for x job because that’s not relevant to other CV rewrites.
