Hi @Anonymous
Thank you for your post. My name is Bogdan and I am with Autodesk Technical Support.
As far as I am aware, for the moment there is no option to export a list of plans or documents, but an enhancement request has been logged on the BIM 360 Ideas dashboard and our Project Management team has marked it as "future consideration".
To see this idea and vote it up, click here. Also, feel free to leave your comments on that thread. Remember, more votes, more chances to see it implemented sooner.
So our development team is aware of this request and they are considering it for future implementation.
I hope this was helpful.
Best regards,
Bogdan
