You can use relations when specifying displacements and rotation angles. For example, when prompted to enter displacement in the Y direction, you can enter:

(where # is the internal feature ID of the NC sequence)

All displacements and rotation angles will be treated as dimensions and assigned dimension IDs; number of instances will be treated as an integer parameter (similar to the number of instances in Creo+ feature patterns). All the pattern information (including the pattern type, dimension and parameter values and IDs, and relations used, if any) will be listed in the NC Sequence info.
