Hi Priya,
It is not available in the standard. You should extend the app.
I always recommend "Auto approval" instead of "Mass approval". Most of users use "Mass approval" for "Blind approval". "Blind approval" is not a good use case from compliance point of view.
After implementing auto approval, approvers will get only important workitems to make a decision. It saves approver's time and Approvers do not need to do blind approval anymore.
