This. At my store I got several subjects made into alerts simply because I saw them on TCM and identified them as previous PMR/KTR subjects from my store. Called the IC, gave them the case numbers and the merchandise stolen, and the subjects were an alert by the next work day. Of course my investigator did recognize a lot of patterns and create alerts, but it is certainly possible to do from the store side.
It blows my mind how often AP team members will know a subject is a repeat offender and fail to use the same INDIV numbers and link the cases. Can't complain about Target not caring about going after ORC if you won't take an extra 2 minutes to write your case up properly.
