Please allow pairing of more than two accounts.

As a freelance video editor, I was just brought onto Client A's team account and which forced me to change the login email for the personal account I had been using to connect with clients up til now. Now Client B is sharing assets to the business email address which has been sucked into the Client A's team space and I can't find a way to share to my personal account (which I had been using for Client B's previous projects) without asking the client to re-send the invitation to the other address. Might not seem like a big deal to ask for  another invitation, but I know from experience that once you have multiple email addresses in any client's address book, it increases the possibility of lost messages and confusion when that client refers other business to you. That's bad enough when I have access to both email accounts and it would be even worse if I ask clients to create an email within their company for me just for Dropbox purposes.

If I were to add folders from Client B (and C, D, E, F, etc.) into my personal folder that is now in Client A's space, I couldn't guarantee the security since Client A's admin could look at those files. Even so, I did a test by added a folder from Client B (with publicly available files for security purposes) into my personal folder on Client A's team space then saved it to my personal Dropbox (both online and drag-and-drop in the Finder)- the result: the folder lost connection with access permissions for other uses- that means I won't see when they add assets and save new versions of project files since the directory is now just a duplicate that exists independently my Dropbox. 

There needs to be an option to add directories for multiple teams under the same login. Freelance contractors are a reality for so many businesses nowadays, it's hard to understand why Dropbox would be designed around such old ideas of how work gets done.
