Multicam program window question

The footage is 3840x2160, and the sequence is 1080x1920 with default media scaling set to frame size.

In the program window, the selected camera shows at footage at 50%, but the cameras 1 and 2 windows displays footage at 100%.  is there a way to show cameras windows 1 & 2 also at 50%?

macbook pro / pp 23.2.0

Thanks
