viewing clients' tax codes

When logging into HMRC as an agent, I can see my SA clients, and if I click on a  client, I can chose an option to see all P2 tax code notifications. However, other than manually checking every client at periodic intervals to see if something has appeared, is there any way of receiving automatic notification when a P2 has been issued? It's not such a problem when I run the payroll, as for P6s and P9s I do get a notification, but I have several SA clients that are employed by employers that I don't run the payroll for.
