Anyone else disappointed that a Sunset and Celestia journal wasn't made as merch

The Journal that Sunset Shimmer wrote to Sunbutt in, and the replies that Sunbutt sent back, in Rainbow Rocks. I mean, I enjoyed seeing the royal sisters get their own published journal, so why was one never made, to show off the entries fron Sunset and Sunbutt, and further eplore their characters and backstory? I would've loved the opportunity to see what Sunset wrote to Sunbutt about, in an oficial journal.
