Edocman module latest and itemid

Hi,

(sorry for my bad English)

Edocman is very good for me, but I have a problem with the module :
In the backend I have to put an Itemid, only one Itemid, to all the categories,

or I have to publish one module for each categories, with different itemid...

I'd like to know how can I do to like automatically with the good Itemid, like with docman

My menu :

Parent_category (Itemid=1)
|_Child_category_blabla (Itemid=2)
|_Child_category_dezdez (Itemid=3)

When I see my edocman module,
when I clic on a document's title, I'd like the link redirect to the good Itemid.

Is it possible ?
How can I do that ?

Thanks !
