Yes, it is.
This is one of the main functionalities of Bloks.
Prompts can be randomized so that each Prompt has an equal chance of being selected with each new session instance. Any Prompt within that Block can be selected. Additionally, if more than one Prompt is being randomly selected from a Blok, then a Prompt cannot be presented twice within the same Session Instance. Stated another way, each prompt will only appear once per Session Instance.
