Medias importer datatype while editing content

A new datatype to mass import medias (images, videos) while editing content would be nice.It would be simplier than :

• create a gallery object, publish it,
• Multiupload medias
• Add a link or embed the gallery object (in an article for example)

A mass upload dataype would simplify this.Uploaded medias should be automatically categorized, and should automatically add object relations.
