Is there a way to make notes visible across all tickets for a requester? For example, lets say Jon Doe has an account on my instance of RT that comes from firstname.lastname@example.org. There are some things special about their account that need to be known. I would like to have those things visible on all their tickets in the header section so, if one of my colleagues gets that ticket they will know about those special things (and add new ones if necessary that would show up on their other tickets as well). They could then take that into account when working their ticket.
Does such a thing exist? Possibily under something like the More about the requestors section of a ticket or alike. I’m using RT v4.2.14 running on CentOS 7.
