BigIP APM Radius Profile

We have BIG-IP in version 11.6.0, I have a question related to RADIUS profile. Under local traffic -> profiles -> services -> radius there are 2 pre-configured profiles: radiusLB and radiusLB-subscriber-aware. I am wondering, if it is possible to configure, which virtual server/pool/access profile uses which radius profile? If I would create my custom radius profile - will I be able to define it in only for one of my virtual servers? If so - where I can do it? I was looking everywhere but unfortunately I got no answer. Thanks in advance.
