You have to erase always a "page" .

To preserve some data in a page, copy it to another page + add new data here. Erase old page.

Next time you want do same, copy to "old" page new dataset , now this is your "new". Erase other page.

And so on...

Or you copy the data you want to keep, to ram area, erase page, copy back from ram , add your new data. (free ram.)
