How to save all responses when using slots in RASA

Good day, everybody!

I need my rasa bot to gather users’ responses (comments regarding customer service) and then save them in DB (for further analysis). What is the most efficient way to do that?

Before, I was trying to use SlotSet; however, it didn’t work the way I wanted. I could only save in a slot one answer, and it didn’t work if a user gave multiple answers (I want my bot to gather as many answers as possible and then save them, as I’ve mentioned above).

Btw, how can I delete everything afterward, so my next user won’t be associated with the responses given before?
