Multiple deals for the same email

Tripi

Hi, today I realized it could be a very good improvement for my sales activities to have the possibility to link one email to multiple Deals. Right now I am working with an agency that is giving me 4 clients and I need to create one deal for each one but we speak about them in the same email thread. 

Would be great to see the same email in each deal but I can't.

Cheers
