how to rename a pdf file saved on *iPad* ibooks without using itunes or the laptop

Hi


Is it possible to rename a file saved on *iPad* ibooks *without* using itunes or the laptop / desktop ?

I know one can synch to iTunes and open each file to change name etc .... but I am looking at a basic function where you can rename the file on the iPad itself , without using a laptop , desktop or itunes



TIA
