I think this should be straightforward, but I can’t figure out how to do it…

I basically want to have a random reply to an comment on my Instagram posts. 

So, somebody comments, I want a store of 7 or 8 standard replies, and I want to randomly reply with one of those…

I just want to reply to the comment - I don’t want to DM, I just want to reply…

Has anyone done this?
