Quick editing of panoramic image yaw/centering?

Ended up shooting a video instead of timelapse on the Fusion. I went ahead and stitched the 100gb of that video, sliding the Yaw slider in studio as usual, to centre the image. However, I missed that Fusion studio centres the rendered video on the initial camera angle, so the yaw correction is useless and I now have a host of frames that all have the same magnetic/gyro heading, but it obviously isn’t always in the direction of travel (which is what I want).

I’ve had a look through pano editing options, and most of it is either Adobe (not paying for that) or Hugin (cumbersome for many images).
Is there an easy/quick option of adjusting yaw/centring of a panoramic image?
