Prepare a section without haste

It would be cool if a section could be prepared without having to do it quickly and running because the previous section is finished. It would be as simple as having to press shift and create to create a section and press create again to confirm when the section is ready.
And to finish the job would be wonderful if you could send the audio signal from that section to the headphones. I suppose it will be complicated, but that point in my opinion would be a great advance for the live performances.
