Maintaining initial offset when copying bone transform

I’m trying to use the copy bone tool to copy bone translation for a suspension. However i want to copy the translation specifically. But copy bone appears to be copying location as well. The documentation makes mention of enable copying location

From the wiki’
The Copy Bone Skeletal Control takes the specified Transform from one bone and copies it to another bone. Be cautious when selecting the checkboxes for Transform. For instance, if you enable copying Location, the Target Bone will move to the Location of the specified Source Bone.’

But i cannot see any checkbox in the editor with this name. Am i missing something or has this functions been moved to another place and the documentation is out of date?
