I inherited this particular project and I received a .qsf file with the pin assignments in it. I also assigned a few last pins with the Pin Planner.

Is the hardware re-used for multiple projects? If it is, then having a common top-level entity definition and associated assignments/constraints file can ease maintenance.
Specific designs then are a component within the top-level entity. This allows you to rename signals from their possibly bland top-level name, eg., GPIO.
