AS3 declarative for parent profile for tcp-wan-optimized

The documentation says you either write your own profile in AS3 or reference and existing, so I do not think it is possible what you ask for. When making a new TCP in AS3 the default parent will be basic TCP profile. Also the basic TCP profile is used when you don't tell AS3 what TCP profile to use.

You may create the TCP profile with imperative declaration like https://docs.ansible.com/ansible/2.8/modules/bigip_profile_tcp_module.html and then reference it in AS3 as shown in https://www.youtube.com/watch?v=b55noytozMU
