Do you mean that once you have imported a Georeferenced PDF Sheet, that you want to add some text onto the drawing and associate that text with the PDF Page and Target Sheet so that you can click on the Text and Hyperlink to a Georeferenced location for the linked Sheet in the Text? Is this so you can move around between sheets easier in Plan View - Are you wanting that to Turn the Target Sheet on automatically (which means changing the View Filter), and when you add the attributes to the text you want to be able to add a Geo Location and or a Sheet and know where its centroid is or something like that - so by clicking the text, you change the View Filter and pan at current zoom factor or Zoom to extents of the target sheet - and display that sheets information.
Is that kind of what you are asking for here?
Or are you asking for the ability to set those up in the Sheet Set so that you can embed those in PDF outputs to make navigation through a PDF Sheet Set created by TBC easier for the target user of the PDF?
Seems like maybe the latter is what you are asking for - is that correct?
