amazon tagging 4 disc set

i have a 4 disc set that has to tagged,
now this is e.g. the 4th disc:

amazon only gives the total files without splitting per cd.
now i have to move all the right files to the bottom so it will rename tracks 43-50 (the 9th is not shown by amazon), but i am only able to move one file at a time it seems?

so i have to push move down 50 times for each file?? is there a way to move the whole block?

another question, why are there no numbers on the right side ?
if i have to scroll the tracks it is not really comfortable to see which track will be renamed with which title..
