Best Answer Feature in Bubble

Dear Rainbow team,
could it be possible to develop a "best answer" feature in a bubble...?

E.g.: Bubbles are often used as a exchange group and so often people ask question's and receive answer's.So the ability to vote or mark/highlight a answer as "best" or "most helpful", we could use the chat as a knowledgebase and finally that would create a new very useful feature for rainbow.Combined with AI we could also enrich this bubbles with standard bot who answers based on this marked answers.

BR & Cheers
