Looking for a program to convert multiple .mp3 files into chaptered M4B file

Hey folks! I'm looking for a Windows program to convert a list of MP3 files into one m4b file that has usable chapters. I found a program merge the files together and convert, but it doesn't keep the mp3 files as "chapters". It just lumps them all together. Any help would be appreciated. Trying to load my iPod up with all sorts of audio books.

 

Disregard! Apparently you can do this in iTunes by selecting the files, right clicking:

Select Get Info
Click on the Options Tab
Select Audio Book for media type
Check Part of a compilation: Yes

Just in case anyone else runs into this program or mods, feel free to delete this thread.
