Hola! hey wondering if there there's a way in pipedrive to "tag" a user to bring a note or file to there attention/notification without actually making a "task" persay.

Example in my case is a rep's sale came in direct to the office, i uploaded a pic of the signed contract but would like to be like "hey @salesrep" so they'd be like "oh cool that came through" or if i had a question about a deal i'd like to pop to add a note and again be like "hey @salesrep, questions about x on this deal" so they could tack on that note..
