Hi Allison - I don't have experience with vendors, but I've seen some clients solve for this using URL parameters to indicate where the link was placed in the email. It's definitely not as scalable as a third party integration, but could at least get you started...
Actually, you don't need to use URL params. The Clicked Email activity can be constrained by the ID of the <a>. So you can have
<a id="top"> <a id="bottom">
And then run a report on each one if you're curious.
