go - Is it possible to have a struct with multiple JSON tags?

Question

I post a request to a server and get a reply in JSON format. I'm able to unmarshal it to a struct. Then I need to create a new JSON file with the same data but different JSON tags.

Example:

In the following code, I get {"name":"Sam","age":20} from a server and unmarshal it to the struct Foo:

type Foo struct {
    Name string `json:"name"`
    Age  int    `json:"age"`
}

Then I need to change the tag name to employee_name and omit age:

type Bar struct {
    Name string `json:"employee_name"`
    Age  int    `json:"-"`
}

After that I send this modified data to another server.

I know I could just create a new Bar and copy all data into it, but there are a lot of fields. I was wondering if there is a way to attach multiple JSON tags like this:

type Foo struct {
    Name string `json:"name" json:"employee_name"`
    Age  int    `json:"age" json:"-"`
}        

Thanks in advance.
