Archivelink Toolbox Change filename attached in PO

Dear All,

I relaunch an old question (2012) with no answer yet :

We are in ECC 6.

We have implemented SAP content Server and Archivelink to attach some documents to BUS2012.

All work properly but I would like to change the display of the attachment list : from ME23N transaction, click on attachment button and choose attachment list. The list of documents stored in SAP content server are displayed.

In the title, SAP put the description of the document type in OAC2 transaction.

and no creator name.

But I would like to change the title with the source file name,  to display the creator name and eventually other informations.

Do you know how to customize this attachement list (via BADI, userexit, ...) ??

Thanks for your help.
