Path/Book Magic question

[Lameth]

Hello All

I am developing a new magic on my horror world, and with the major help of two posters here [many thanks!] its being formed. Its basically Book Ritual Magic, but I have a question.

an example: One of the PCs was trained to be a cinematic Occultist. Basically trained to know about the supernatural and the many ways of magic throughout the world and throughout time, true and not. She was instructed to use some of these ways, and also how to find out how to use a way she does not know yet. So far the ways she was trained in was Norse Runes, Egyptian Sorcery, European/Middle Ages Sorcery, Enochian Magic, and Roman/Greek high magic rituals.

My question is due to the fact that she was trained with rituals by rote, and not allowed to make up rituals this is Ritual Book Magic, I got that. But is this the way it would be set up?

Ritual Magic [Egyptian Sorcery]. Path [Rituals of Isis]. Then techniques under that as the rituals themselves
Ritual Magic [Enochian Magic]. Path [Wards of protection]. Then techniques under that as the rituals themselves
Ritual Magic [Roman Magic]. Path [Way of Juno]. Then techniques under that as the rituals themselves

Or

Ritual Magic [only one general core skill].
Path Egyptian Sorcery, general of all Egyptian magics.
Then techniques under each Path of the rituals themselves
Path Enochian Magic, general of all Enochian magics.
Then techniques under each Path of the rituals themselves
Path Roman Magic, general of all Roman magics.
Then techniques under each Path of the rituals themselves
