unfortunatelly not.
The TRACK & the TITLE fields have a fixed place in the web sources structure of Mp3tag and can't be changed by any scirpt.
I have tried serveral things to work around this, my small success is described here: /t/11831/1
You can add this code to my script with the "TEXT OPTION: FREE WEB SOURCES SCRIPT CODE FOR STANDARD SCRIPTS" field of the setting mp3 file. But as I mention in the linked thread, the solution seems to be somewhat unstable.
And you should also test what happens when you come to a release where TRACK TEMP is not written (standard 1 CD releases).
Personally, I handle this problem with this stored action group, which I execute after the web script use at double CDs:
Action: Format Value
Field: TRACK
Formatstring: %discnumber%$num(%Track Temp%,2)
This gives you tracknumbers like 101, 102, 103, ... 201, 202, 203, .... For your desired format, leave away %discnumber% in the formatstring.
edit:
Or you can use Mp3tag Autonumbering Wizard, if you have the different discs in different folders. Press Ctrl + K and check "Reset counter for each directory".
