Rotate Footage 90 degrees in Source Window to View Verticaly
I have a mix of horizontal (1920x1080 footage) and vertical footage (1080x1920) shot on my Sony A7III that I'm sorting through and creating subclips from. I'm viewing the footage in the Source window and creating subclips to review later, so I don't want to have to drag individual clips into my Timeline / Sequence.
My question is - is there any way to rotate a shot that appears horizontal but was actually shot vertically so that it appears vertically in the Source Window? When I apply the transform master clip effect it rotates the video within the contraints of the previous aspect ratio, whereas I'm looking to flip the entire orientation of the video.

Thanks everyone!
