Batch Converter - Tracks/Total Tracks Count

Hi,

Is it possible through use of ID Tag Update - Manipulation - Rule Based Manipulation (or any other way) to update the track number from being single digits (1, 2, 3, 4...) to be double digit/total tracks (01/15, 02/15, 03/15, 04/15...)?

I've tried using
IF Track=1
SET Track=01
IF Track=2
SET Track=02
etc.

which seems to work to get the double digit bit, but is there a more elegant way .. something like
IF Track=n
SET Track=nn
?

Secondly, does the total number of tracks get stored in a tag field during ripping so that it can be called back later - like now!?
If so, how do you call it in ID Tag Update?

Thanks in advance

It might depend on which audio format you are using, it might not be possible for the tag to store a '0' internally.
