It would be helpful to have a very easy, straightforward way of including "flyers" in pdf format directly into a campaign email (i.e. NOT using a link to go to it). The "block" menu on the right has an "image" button ~ which makes adding images easy. In fact, I often just end up taking a screen shot of my flyer and inserting it as an image since it is so simple. if you could add a button that would do the same for a pdf it would be great.
