NEC 3 compensation event - forgotten impact from a closed CE

Hi, Good day. A previous CE is already closed with no time impact and only cost implication. The Contractor withdawn its time impact in that CE because of conflict with the PM assessment. Now, another new related CE is being prepared which includes a forgotten change of quantity which has a time impact (different issue from the conflict) in the previous CE. Can the Contractor do that or not, include the other changes in the previous CE into the new CE? Any related NEC clause? Thank you. Regards, Dj
