Seamless Transition between ChatGPT Versions

I would like to request a feature that enables a seamless transition between ChatGPT versions 3.5 and 4, without the loss of conversation history. Currently, when version 4 is available and exceeds its usage limit, the conversation reverts back to version 3.5. However, there is no mechanism to switch back to version 4 once it becomes available again after some time. This feature would allow users to continue their conversations in the latest version without the need to start a new chat, ensuring a smooth and uninterrupted experience. By retaining the conversation history across different versions, users can benefit from the improved capabilities of each version while maintaining context and continuity. I believe this feature would greatly enhance the usability and flexibility of ChatGPT, providing users with a more cohesive and efficient chat experience.
