Another small issue in animation

I am noticing that when the first frame of an animation is created from an image, the default s/60 is 6. But when you add more frames they have the value of 10 by default. So in order to make them all the same, it is necessary to select the first frame and change it to 10. Then, if you want to change all the frames to different number, you can select them all and change them all at the same time. It would be better if the first frame and all the subsequent frames were given the same value by default. Is there some way to adjust this?

Thanks,
