Add a comment thread on coursepress units

Is it possible to add a comment thread inside a unit of a course? The instructor would like to be able to comment on the units in the same way you would comment on a typical wordpress post. I have found a plugin from a different developer that would let me use a short code to add a comment thread anywhere, but I have no way to know if these short codes will work within coursepress text box elements. I wanted to ask before I invested in another developer's plugin in case you had a better idea of how to do this.
