Currently, if I am looking to bring on a new team or import multiple projects from another data source, I can use the "CSV Import" functionality.

Unfortunately, this functionality only allows selecting 1 CSV file at a time, so if I have 100+ projects to import (or even a few dozen), it requires a lot of manual work.

If the CSV import file selector allowed you to select multiple CSV files at once and import them in one go, that would save a lot of time.
