Is it possible to burn cds (flac) with txt files, st5/shn and jpeg files?

I know with DVDs you can create a folder called EXTRAS_TS and put all the extra shit in that. But how would you go about with audio cds? I know you can do this is if you burn the FLACs as a Data Disc. But is it possible to burn them as an Audio Disc so I can hear them in my car including the artwork, info files etc...

Do you just create an 'Extras' folder in Nero or how? Need to burn as an audio disc and not data
