Fck upload folder and template in Session ?!

---- PHP USER ----
Hy everyone,

I juste would like to know if I can specify the download folder (Config['UserFilesPath']) with a session like:

$oFCKeditor = new FCKeditor('mytxtarea') ;
$oFCKeditor->BasePath = $_SESSION['fck_folder'] ;
$oFCKeditor->Value= "Hello World>" ;
$oFCKeditor->Config['UserFilesPath'] = $_SESSION
['my_upload'] ;
$oFCKeditor->Create() ;

Cause I would like specify one folder by user by this way.
Is it possible to do the same thing for the template file ?

Someone can Help me plz ?
Thx a lot !!!

sorry my english is so bad :S
