Can find Join CD command itunes 12.2.1 on Windows 8
I am running itunes 12.2.1.16 on a Win 8 machine. I want import some Audiobooks into itunes and want to use the Join CD command to join all the tracks on each disc. I cannot find Join CD on this version of itunes. The Help info seems to be wrong as the Options button referred is not there and the Options shown on the CD import screen does not offer Join CD as a selection. Can someone help me find this or tell me what I am doing wrong. Many thanks
