Seeking assistance for MS project

Hi Team,

Can we use 'Expected Finish' or 'Projected Finish' in MS Project in a similar way to how they are used in Primavera P6?

For instance 

If a Contractor or Consultant commits to completing work by a date that differs from the baseline plan, how should the project schedule be adjusted to reflect these new dates? For instance, if the building structure was originally scheduled for completion in August, but the contractor has now committed to finishing by November, what is the best way to analyze the impact of this change on the overall project timeline in MS project?

Regards 

Abhishek
