Is your feature request related to a problem? Please describe.
Currently entries cant change dynamically when conditions are met, like they worked on the thaumonomicon, where the first time an entry unlocked it only displayed some lore and instructions/tips on what to do (eg. go to 300 blocks high, craft certain machines, find certain items/structures, etc...) and only after completing those tasks would the final version of the entry be revealed with the more detailed description of what the entry was about. Sometimes entries would even have multiple intermediate stages before fully unlocking

Describe the solution you'd like
A way for entry contents to be changed/updated when a certain condition is met. This could be adding new pages, replacing existing pages, changing the contents of existing pages, etc....
