Does Vowles regret not replacing Logan Sargeant earlier?

After a difficult stint at Williams for Logan Sargeant, team principal James Vowles made the call to replace the American with at the time Formula 2 driver and Williams junior Franco Colapinto ahead of the Italian Grand Prix. Since then, Colapinto has already scored his first points, and left a good impression on the paddock. Therefore, does the Briton regret not making that switch earlier?
