"TCS" Functionality on Big Iron
Many private/business jet aircraft (Citations and Lears and at least some of the bigger Bombardiers that I know of, presumably others) have a TCS function as part of the autopilot -- one one-touch button that deactivates the autopilot while held to allow a brief bit of hand-flying and when released reactivates the autopilot synchronized to the new heading/attitude/etc.
Does this functionality exist in the commercial world? What about regionals (were I could imagine the ability for some quick hand flying would be more valuable)?
