Actually, there is a third way, which may be easier in this case: make a single-column cifti file from the one you have (either copy it or use -cifti-merge to select one column), and then use -cifti-replace-structure on it, with the curvature metric files. Note, -cifti-replace-structure modifies the input cifti file, this is why you need to make a copy first.
