Root 6 Histogram Drawing

I would like to associate some text with the histogram object itself (not the title) so that after it has been saved to a file, re-opening the file and clicking on the histogram in TBrowser the text is drawn along with the histogram.

I understand I can do this with a text box on a canvas and save the canvas, but it would be nice to have it be a part of the histogram object so I don’t need to write canvas’s and histograms to the file.

Is this possible?

{
   TH1F *h  = new TH1F("h","h",100, 0,1);
   TText *T = new TText(.5,.5,"Text");
   h->GetListOfFunctions()->Add(T);
   h->Draw();
}
