find/show pdf highlights in large documents

When dealing with large pdf documents numbering serval hundered pages, how does EndNote deal with

A. indicating that there are highlights / notes in a pdf document attached to a reference?

B. allow the user to locate the highlights? such as the summary of the highlighted text that auto scrolls document to correct section i’m familier in other products

I know you can open up the pdf in acrobat, but that rather negates the point of having the viewer, and is a very slow process if you want to make changes.
