New Bulk PDF Invoice Generation options

For the Bulk PDF Invoice Generation we can export based on dates, invoice status, and buildings, but could we also get an option to generate it based on grade? This way we can pull the invoices pased on grades like when we are working on getting items together for the 12th graders working on there graduation checklist.

Pulling it by the building is doable, but adds an extra step to sort out the other 3 grades we don't need.
