Logging Emails(With Body) to Opportunities

I have a customer who is using JO to log emails to Salesforce. So far they are very happy with this feature and really like that it provides the body of the email sent but would like to also do something similar with opportunities.



Currently they have kind of a workaround for their renewal reach-outs and have some rules made that logs these outreaches on the opportunity level. Unfortunately these logs do not include the body of the email because the body is not stored on the email logs object.



So I suppose I would like to start a discussion on the possibility of doing this.



Thanks!
