Hello, Erikari. You might have misunderstood what I was asking about. This is an example of a chain of Bones that I usually make.

Often times, I am not satisfied with the length as I make it for images that require Weights based on these bones. So, I tend to change the Bone Scale to match the images. My eventual setup is complicated to explain, but I usually keep these bones at equal Bone Scale.
The idea I am presenting is an easy-to-access button that moves the selected bone to the end of their Parent bone based on its Bone Scale, instead of having to input the Child Bone's Translate Parent X-axis manually. So the automatic process would be like: Child Bone's Parent X-axis = Parent's Bone Scale. This would eliminate the need to Undo and repeat the process of moving the bones as well as keep the bones aligned efficiently.
