According to MPEP ¶ 2.33 : Any request to add an inventor must be in the form of a request under 37 CFR 1.48. Otherwise, the inventorship in the CPA shall be the same as in the prior application. This means that if you want to add a new inventor to a CPA, you must file a formal request under 37 CFR 1.48 , which outlines the procedures for correcting or changing inventorship in patent applications.
