How to create random junction (flow) ?

Hi there, is there a way to create a random function to assign different flow/sequel automatically?

It's similar to "add player decision node (button), but.... I want the flow to be random, and user didn't have to choose anything.

I'm building some kind of "psychological bot" where the user can tell the bot their feeling.

So the user will keep telling the same thing everyday. like I'm happy, I'm sad, etc

I want to give more impression of "humanism" by adding random factor there.

I let's say a user will say "I'm happy" then the bot will randomly assign 30 different type of flow/sequel it without the user have to choose. So the user can keep telling the bot "happy things" every day in a month without getting bored.

Because if the bot keep using the same flow, it will feel very robotic and makes the user get bored really really fast and stop using this bot everyday.

But if user have to choose 30 alternatif. It will be too much for them.

Thanks
