We do not put much effort in development of editing tools for cameras because they are intended for occasional use only.
Better to concentrate on improving the quality of calibration video. This is not very hard, but requires some practice. With good video, there is usually no need to set initial camera positions at all as they are detected automatically.
Please read all the tips in our docs carefully:
