View Marketo Emails in Salesforce

We are looking to send Marketo emails from Salesforce by clicking the button. From there, the next screen allows us to choose a "template," which populates a few emails from Marketo. I couldn't figure out a way to get emails to show up in that view for our reps to use them for their outbound prospecting. Any ideas? I cloned the Program within Marketo that houses emails that show up in there already, and it worked initially; those emails in the new program no longer show up. We also can't drag new emails into the old program. There must be an easy way to do this. Thanks Marketo community!
