Importing files to a group owned library

I am setting up a seafile pro server using 6.3.2. During the setup process I created Departments which own a library. Now I am looking for the “best” way to import the files from an external source into the group owned libraries.

I tried the “Import Directory To Seafile” script but it seams to only import directly to a user owned file and I cannot figure out how to specify the Group as the directory owner. I also could not figure out how to transfer ownership from a user to a Group.

The files total about 800 GB.

Thank you for the help
