Associate emails with accounts

Associate emails with accounts

I can manually associate phone calls with accounts, but the same cannot be done with emails.  A fix for this needs to happen ASAP. 

Here is an example:

Attorney John Doe sends me three emails.  The first one is regarding Tom, the second one is regarding Dick, and the third one is in regards to Harry.  I need to be able to associate each of the emails to the respective accounts for Tom, Dick, and Harry,
