Change default settings in LTM configuration

Thanks for your answer, I choose a bad example I'm sorry.

My request is global, I would like to change the default value for a lot of parameters in a BigIp, a better example : when I create a new Pool or VS I would like to have my defaults values and not the bigip defaults values. For example when I create a new VS I would like to have "my_http_profile" by default and not "none" for all my new VS.

Thanks
