go - golang function alias on method receiver

I can create method alias for an usual method:

func method1() {
    fmt.Println("method1")
}

var Method1 = method1

But cannot do the same for a method receiver:

type Person struct {
    Name string
}

func (p *Person) methodReciver() {
    fmt.Println("method reciver")
}

var MethodReciver = methodReciver

In this case I got the error on line var MethodReciver = methodReciver:

undefined: methodReciver

Full code:

package main

import (
    "fmt"
)

type Person struct {
    Name string
}

func method1() {
    fmt.Println("method1")
}

var Method1 = method1

func (p *Person) methodReceiver() {
    fmt.Println("method receiver")
}

var MethodReceiver = methodReceiver

func main() {
    method1()
    Method1()
    p := Person{"Nick"}
    p.methodReceiver()
    p.MethodReceiver()
}

Playground

Is it possible to create a method alias for methodReceiver?
