ScanRedirected

Hi all,

I have seen there is a nice way to put the tree data in ascii file by doing
(TTreePlayer*)(T->GetPlayer()))->SetScanRedirect(true); T->Scan("*");

or doing:
  TTree *T = (TTree*) f.Get(l_namestructure);   ((TTreePlayer*)(T->GetPlayer()))->SetScanFileName("toto.txt");

But what i'd like to do is to add some information at the beginning and the end of the file in a loop.

So i'd like something like:

info1
Scanning info for tree1
info2
Scanning info for tree2

etc...

Is there a way to do that in a few simple root commands ?(so to append informations in ascii file toto.txt ? )

Thanks in advance.
