Group Jive - Gallery - upload

Can you create optional fields on Gallery in a Group Jive Upload Files.
1. Can you create extra fields (custom fields) when a file is uploaded to store extra details on the file, like a comment box in addition to the description.
2. If you upload to group jive, can you stop everyone seeing your uploaded file apart from the owner of the group. I know the purpose is to share information but I am trying to use it for a specific purpose.

I want to use it so that students can upload their work, but they cant see other students work, but the teacher who owns the group can see all the work. I then want a custom box so the tutor can add information to file properties in addition to the description field that is there.

Cheers.

No, they already include a description where you'd put your comment. CB Gallery can have commenting using CB Activity and CB Auto Actions though. GJ can not have commenting.

Only if approval is enabled then it'll be pending approval and only visible to the group owner, group moderators, group administrators, cb moderators, and the owner of the file.
