Review functionality suggestion...

Hi There, I write complex technical documents and supporting e-learning courses. The structure of my courses generally match the structure of the documents, which is like this:

Each main heading in my document is a slide in Storyline.

Each subheading of the document is a layer in the corresponding slide. 

So it will look like, a document may have a structure like: Heading 1, Subheading 1.1, Subheading 1.2, Subheading 1.3. The e-learning course will then be structured accordingly: Slide 1, Layer 1.1, Layer 1.2, Layer 1.3.

The problem with the review is that when someone makes a comment about a layer, I can't know what they are talking about because the screenshot capture is of the main slide layer, not the layer they are viewing.
