Autopopulate discnumber field with first character of track

Hi there - so, I'd like to take the first character of the track field (when applicable to my usage) and have that character populate the correlating discnumber field. For example, if the track field contains a value that is "A1", I would like have some sort of action that will automatically populate the discnumber field and set it's value to be "A".

Thanks in advance.

Try Convert>Tag-Tag or an action of the type "Format value" for DISCNUMBER
Format string: $left(%track%,1)

thank you - the action works perfectly. I appreciate your help with this :slight_smile:
