Choosing File Details to Include

When syncing my device through WMP using WMA files all the file details (such
as artist name, album name) were transfered with the file. However, when I
tried to sync MP3 files the only info that transferred was the file (song)
name - it also had included the the track# as part of the song name.

Last night I THINK I came across a window where I could check off which
details to include and also had the option to remove the track # from the
song name.

Today I cannot find that screen anywhere.

Where would I have seen such a screen and how do I find it again?

Thanks
