Page names and importing from dwg

Hi Everyone,

I have a couple hundred dwg's that I'm importing to one large PDF using Acrobat XI.  It is working great for the most part.  There currently is some sort of associated page tag or title that is part of each page from the import process.  Currently it looks like this tag or title is set to the paperspace title which for all the dwg files happens to be 'Layout1'.  I can obviously go into each dwg and rename the paperspace tab as per the drawing number, but I was wondering if this property can be found and edited within Acrobat?  I've looked everywhere and can't find this tag.

Thanks very much for your help!
