ReportViewer number page per id

Hi, Im working in a rdlc reportviewer to print instantly a masive pdf

I need to add a Page number in my pdf report, but need to add a page number for each id(sql column id) in my report 

Right now when I create a report I have this: "Page 1 of 72" , "Page 2 of 72", "Page 3 of 72" etc...

My report create 2 document for each id.

And I need a number page like this: "Page 1 of 2", "Page 2 of 2", "Page 1 of 2", "Page 2 of 2"  etc.. for all 72 documents

Im using a List control, inside this list control Im putting another controls for crear the 2 documents

The pagenumber control(textblock) is  in the footer layer

How can I do this?

thanks
