We have a bunch of automation in place to handle deals (or copies of the original ones) after we have WON or LOST them. My point being today is that it would be extremely useful to be able to link emails to multiple deals to not lose track of the communication history. 

At the moment only one deal can be linked to an email address and once You change that linked deal => the complete history of all email communications transfers to the new deal which is far from ideal as I consider the WON DEAL as my reference point and base my search on.
