Using the %{disk} tag in the rename format doesn't work
I wanted to renumber some files from a two-disk set using the format %{disk}%{track} %{title}. My files (m4a ALAC) were properly tagged (they contained both the track and disk number tags), but upon using the rename from Tag 2 button, the filename was set to "xx title.m4a", ignoring the %{disk}.
I ended up manually copying the disk number to the comment tag and using the %{comment}%{track} %{title} rename format, which did work.
The help file specifies that any frame name could be used, so I tried both %{disk} (the mp4 frame name) and %{Disk Number} (the unified name), to no avail.
