Prevent automatic model switching

Hello,
When we use the Opus model, if we run out of tokens in the middle of a task, it switches to the Sonnet model. However, on complicated tasks, switching models leads to poor quality code, and 90% of the time we need to erase everything and restart the request.

Is it possible to add a flag like --no-switch-model to stop the current task so we can continue later with the current model?

Best regards,
