Hi,
You will found it in the menu "windows -> hierarchy", or Maj + F11.
That opens the Hierarchy structure of your pdf.
There you will find the items pageType, pageArea and ContentArea( a symbol of a page with a rose coloured target.
So what i did on my document was: Menu "edit" ->"select all static objects", you group them and then you transfer them to the contentArea in the hierarchy panel.
I test this for the moment with one page only but on this page i have an very heavy field entry where i have to go through by tabulation and i saw that the tab speed got faster from 2 seconds for each tab to 1 second. Better something then nothing...
regards
