Metadatas functions and mp3 tags...

My question is:

- Is Adobe media Encoder able to convert the mp3 tags as "metadata" automatically when exporting in the mp3 format?

>>> If yes: how should we adjust the assimilation parameters? ie. "preconfiguration" panel under "File metadata"> "Add metadata to the file"> "create a new preconfiguration" add a metadata key? (I tried "artist" "artist" "title" "title", "comment" "description" ... nothing works

>>>> If not:
a / how can i make so that the mp3 tags are preserved in the end... even if I do not check the box "Metadata of the file", I end up with a file whose tag "title" was modified with the filename ... and other tags ... empty
b / with what type of file does the "metadata" setting work? for what type of metadata?

Before calling the support community I of course went through all the tutorials which are not PRECISE ENOUGH on the subject ...
