Will AP World History get its Part 4 mastery questions?

Now in the AP World History, the 3th Part (600-1450) only have practice questions, while Part 4 (1450-present) simply has nothing to practice. Are there any plans to complete those questions? I am taking AP world history next year and can really utilize the practice questions.

P.S. If it's possible to AI-grade essays in SAT practice, is it possible to provide us with written prompts training for History/Geography courses? Thanks :)
