Śrī Matre Namah!
There's not much else we have in addition to what is already in the manual. At the moment sanskrit version is not yet ready.
For more information you can read Guruji's "Understanding of Sri Cakra Puja" (which has also been included in Michael Bowden's "Gifts from the Goddess" book) where he describes each enclosure and its symbolism.
There are also a number of playlists on SoundCloud where Guruji is talking about the symbolisms of Sri Cakra its enclosures and deities.
