Can you define what you mean?
Certainly you can center other features, or patterns of features on the "center line" of the datum feature (not sure that wordings quite right) ASME Y14.5M-1994 section 5.- figure 5-4 & section 5.13 - figures 5-59 & 5-60.
Are you saying you want to offset things from the center?
