Thank you @ohrenkino - I will use this!

Would it be possible to implement a "contains" string function for to make it possible, @Florian ? Similar to the equal function? Or would that be too resource heavy or complicated?

And another question (it is related, I think!), is it or could it be possible to pull and automatically set track number and total tracks from the tag source?

Example:

 ![track-number-total-tracks](https://community.mp3tag.de/uploads/default/original/2X/d/d5b94bbe8dc751fb8635fc8dc47403ed4e9769fc.jpeg)

Here it found the TRACK = 5, I move my file to line 5 to assign it to the correct track but if Mp3tag could read out that the album has a total of 7 tracks it might be possible for it to automatically add that at the end of the track field (i.e. "5/7" instead of just "5")? It would save a lot of time by not always having to manually set track data in the track number assistant (Cmd+K). I can see that it might mess things up a bit in some cases, but as an optional switch would be cool.
