Playlist [*.xspf] Editing several entries at once with vlc

[R2D2]

I want to save streaming URLs of podcast episodes in a *.xspf playlist.

When I add an episode to the playlist, save and reopen it, the title information is that of the filename.
For example
wdrzeitzeichen_2019-10-04_rembrandtvanrijnniederlaendmalertodestag4101669_wdr5.mp3

The media information of the original podcast entry can be modified with vlc:
For example,
adding the radio station and the name of the podcast "WDR - Zeitzeichen" as a comment:
[right click on the episode -> information -> [Media Information] [General] Comments "WDR - Zeitzeichen" ]

If the podcast episode is modified in this way and then added to the playlist, saved and reopened,
the titel information has changed to:
Rembrandt van Rijn, niederländ. Maler (Todestag 4.10.1669)

Is it possible to modify the media information for several entries at once?
