亲属移民可以用EB的排期吗？

现在F2A出现排期，如果之前有EB的排期，可以用在F2A申请中吗？

USCIS的policy manual里没有允许这种情况：

Using Earlier Priority Dates

An applicant may intend to use an earlier priority date than the one indicated on his or her latest petition. This situation may occur when the same petitioner in a family-based category has filed more than one petition on behalf of an applicant for the same classification.[27] It may also occur in certain employment-based categories. Specifically, in the event that an applicant is the beneficiary of multiple approved employment-based petitions filed under 1st, 2nd, or 3rd preference, the applicant is entitled to the earliest priority date.[28]
