Is there a way to copy and paste all keyframes from one bone to another, across all layers?

The only solution I've found so far is using 'Copy Deep Frame Range.' However, when I paste it, the keyframes are applied to every single frame make it impossible to edit later, which is far from ideal. The other method involves manually copying the keyframes from each individual layer and pasting them in the desired location, but this process would take forever if I had to do it for every layer.
Since I’m working on the animation and sometimes need to control the individual vector points in certain layers, I need a way to copy everything and paste it into an action. Is there any way to do this more efficiently?
