How can I get my Export config to print for each track, that track's duration as a %age of all tracks' duration? I.e.

$loop(%dummy%)  
$div($mul(%\_length\_seconds%,100),%\_total\_time\_raw%)  
$loopend()

except this doesn't work, because %\_total\_time\_raw% is invalid inside the loop. I can find no way of carrying a valid %\_total\_time\_raw% into the loop.

Thanks.
