Hi, I'd like to be able to tag multiple mp3s of different artists and albums with all the missing fields.  
For example, in my collection all the files have the correct tags for artist name and title but in some cases they lack covers, year, album, or other. Is there any way to complete mp3s with missing tags without having to search one file at a time?  
Basically a multiple tag that exploit the data present to fill in the missing ones.  
If it does not exist could this function be implemented?

This would require that MP3tag compares data between files.  
Which it does not.  
So the best way would still be to load all the files, then filter for each missing field and with perhaps another filter, add the information e.g. using the tag panel.

How can I use the filters?  
Where I find that?
