Actually @jpv2212 you don't have to submit the old passports. They don't verify travel history from Pakistan. You can freely move within schengen without getting stamped, However your travel history has to reflect your travels.
The passport purpose is:
Purpose
To confirm the applicant's identity
Document requirements
A clear and legible copy of the biographical data page of a passport or travel document must be provided.

They need current and valid passport only, and any other pages with visa, stamps, markings etc.
