Show Contact Emails in Associated Lead Module?

Show Contact Emails in Associated Lead Module?

Is there a way to show all emails in the Lead module for Contacts associated with that Lead? I've sync'd my Outlook with Zoho CRM so that when I email a Contact, it displays in the Contact module. I would also like that email to display in the Lead module to which that Contact is associated.

E.g. 
Tim Smith is the Contact at Widget Co.
I email Tim and the email is displayed in the Contact module for Tim
In the Widget Co. Lead module, I also see the email that was sent to Tim <--This is where I need help

Any ideas?

Thanks in advance for any help you have!
