Astarria_Draglionz Well, there's no "easy/comfortable" way to do this.
I would activate "Use volume keys to turn pages" option under options, then activate "auto-unlock next chapter" on the novel you want to unlock & I think your reading mode must be scrolling for this to work.
Then you just go through the novel using the volume keys and unlock the chapters till you have unlocked as many as you want (or run out of SS).
Have fun! 😆
