Mailchimp Integration - options for number of lines displayed

Currently you can either display 1 line, or the entire description of an event in Mailchimp. Please make it so that you can select something in between. It doesn't have to be so flexible that you can select any amount. But something more like 3 or 4 lines would be helpful. Sometimes 1 line is not enough information about an event to capture the interest of the reader and get them to click the "read more". But the entire description is way too much for the email (especially when you have multiple events you are trying to fit in). So an in-between option would be really helpful.
