YES, that is a must! Coming from Pro Tools, my main workflow has been smashed in Studio One ever since. That beeing: Having two mono tracks (for two mics) on RECORD for my acoustic guitar. After recording I grab these two tracks and put them on a stereo track. And keep repeating...
And IF there was a phase problem (which I usually check first), the other way around (= drag one stereo track on to two mono tracks) is a MUST, too. That's so intuitive in Pro Tools. In S1 this is a hidden command somewhere in the browser..
Please fix this! Thanks a lot!
