Winbuild questions

I started my second winbuild after the first one seemed to work okay. I wanted to try adding different apps to my project so downloaded the ppApps_PX01 package, unzipped it and ran the LX.061412.exe. I wanted to add my own apps/utilities, so as a test I added Hitman pro.exe, put it in a folder by the same name, copied the ppApp.ini file from another app folder, then added it to the PPapps folder in the root of my C: drive. I did the same for the adwcleaner.exe file, then ran the build and burned the ISO file to a cd-r. When I booted to the live cd, Hitman pro and adware cleaner weren't there. I'm not sure if I'm understanding the tutorial correctly. Is it possible to add my own apps to the project?
When I select the backup current base to make an archive of the project, where does it put the file?
Thanks for all your help. Winbuild really is a really great program.
