Request: Save Email as Template

I would love to have the ability to utilize emails I've created in campaigns in Canvases. But the only way to do that is to export the email out of campaign as a .zip file and then import it into templates. This then removes the best part of the email creation and editing process: drag and drop! 

So then I can no longer edit the email in the canvas without digging into the code.

Anyone else have this problem? This is a feature I've been able to use in other email marketing services like hubspot! 

Would love a "save email as template" dropdown option. Or, when I'm creating a canvas, be able to select emails that I've created in campaigns.
