Random bot message showing again with the same message

If I want to remind the participant of my bot with the same bot-message as one of the previous interactions (which is generating a random bot-message from 3 options), what should I do?

Also, if I want to send a bot-message with 3 randomized different sentences (e.g. named A, B, and C) . For example, it shows A this time. Then, in another interaction, I want to send the bot message with the same sentences except the one shown before (which means showing one sentence between B and C). For example, it then shows B. Finally, in another interaction, I want to show the last sentence which didn't show in the first two interactions (this time is C). What should I do?
