Apart from Susannah and Bel and the Dragon, there is a third excerpt from Daniel that Protestant Bibles place in the Apocrypha. They title it The Song of the Three Young Men. It’s part of Daniel 3 in Catholic Bibles.
I suspect it may not even be possible to trace the history of the OT canon in such a detailed manner as you are proposing here. The early lists, such as the one approved at Pope Damasus’ Council of Rome, for instance, simply name the books without describing their contents. So when we see the entry “Daniel, one book,” that’s it, that’s all there is to know about it. Bear in mind that the books of the Bible weren’t even broken up into chapters until around 1190, eight centuries after the Council of Rome. Even if Jerome and the others had wanted to include some information about the contents of each of the books on their list, there was no easy way for them to do that. They might have given a stichometry – the number of manuscript lines – but that would be pretty much the limit.
