Hi @MarkMaldaba,
Thanks for submitting the feature request!
As for that integration, it looks like it will check if the post has a ticket number in it and if it does it will post back into the same channel with ticket info and presumably a link to the ticket on Jira. It won't edit the original post though, and it might get a bit spammy if your users are talking with ticket numbers all the time.
I'm not sure if that's good enough for what you're looking for but it might be useful for you in the meantime.
