When sending/publishing a column from grade book to Google Classroom, it only shows the title of the column on Google Classroom. There is no description.
May I suggest:
1. Ability to add description before sending to Google Classroom as an assignment.
2. Ability to add links.
3. When working with iDoceo Connect then sending to Google Classroom as an assignment to notify students, a link to connect.idoceo.net automatically added on the assignment.
I have attached a picture, the first one is straight from iDoceo column to GC. The second one, I have to go back to GC and edit the assignment and add the descriptions & attach links. Hope it makes sense!
