Having multiple "AppNamePortable" launchers for a single app

I have minimal experience when it comes to making apps portable (though I have had some success with some smaller stuff), and while I have the basics down I wouldn't quite say I know all the ins and outs of the PAF format. I'm trying to make a portable version of an app that has multiple components with their own executables and I want them all to have their own launchers similarly to LibreOffice. I tried looking at how LibreOffice does it and while I understand the naming of the various launchers it wasn't quite obvious to me how all the different launchers were generated, as LibreOfficePortable.ini only listed soffice.exe and not the other components. Is there any specific file I can edit or something to make a similar setup?
