For Notificiation-Initiated Sessions (NIS) and User-Initiated Sessions (UIS), you can select the number and order of prompts that are delivered to users. Sometimes you might want to deliver all of the prompts that you create for a session, and in a specific order. In other cases, you might vary the user experience by delivering only a subset of prompts (you can establish the number) for each session and presenting them in random order. NIS and UIS are made up of “bloks” of prompts. While most creators use only a single blok of prompts for their sessions, you may create multiple bloks and establish different prompt selection rules (eg, blok1 might present all prompts in order and blok2 might present 2 of 10 prompts each session and draw those randomly).
