Enable Track Changes on Interactive Form

Hi,

I have an interactive form that I designed in LiveCycle Designer 8. I've set the distribution rights using Acrobat Pro to enable my Reader users to fill out the form.

When the completed form is returned I would like to add sticky notes and text edits using Pro, but Acrobat restricts the use of markup tools to static PDF documents.

Does anyone know how to allow the use of markup tools on interactive documents?

Thanks!

Andi
