Unfortunately not. With Apex, you only get one email alarm outlet. As ca1ore mentioned, the first line of the email will tell you the programming statement that caused the alarm. That could be of use depending on what you're trying to do.
I'm not sure of the intent of your "Change Sock" reminder... if it's just a reminder every XX days, or if it's every Sunday, or if it's when flow decreases below a certain level somewhere. Depending on the scenario, you could have some type of virtual outlet set up to turn under certain conditions and that outlet could be named "ChangeSock". When that outlet is triggered, and it's in your alarm statement, then the email would mention "ChangeSock" in the first line of the email.
I don't think it's what you're looking for, but it's probably better than nothing.
I don't use Fusion, but I'm thinking I heard there is (or will be in the future) some type of "reminder" page or service. Maybe someone with experience there can confirm or deny.
