Collaborative Review of Adobe Acrobat Portfolio

Hi All,

My question is related to Acrobat Portfolio; however it is Technical Writer related...

When we publish multiple documents and combine them in Adobe Acrobat Portfolio.

Is it possible to do an Adobe Acrobat Collaborative Review of Acrobat Portfolio file, which is also an .PDF file???

I asked this question here in hope of getting quick response.

Adobe Acrobat forum has questions for days, unanswered.

Thanks.
