Hi Adam. Hope you have recovered from Dreamforce... what a busy week!

We have a requirement for users to be able to classify files they attach to an opportunity. Think of a picklist that describes what kind of file it is. Despite all the ways we can connect a file to an opportunity (Notes & Attachments; Chatter File Post; Upload the file to a library and post the link to the opportunity; Upload the file to a Chatter group and post the link; etc...), I can't think of a way to add anywhere a custom picklist or create another mechanism to require users to properly classify the file. Can you think of anything?

Thanks.
