Navigate to another page but make the "back" button go home?

I have a home page and I navigate like this to various pages.

Home -> A (back) -> Home

Home -> B (back) -> Home

Home -> C -> ( back) -> Home

I want to go Home -> C. and then from C… i want to go -> A but if you hit the back button, i want it to go Home, not back to C. Is there a way to do that?

Home -> C —> Optional Route to A --> (back) --> Home.

You can override the back-button behavior on an individual page

Import Navbar

import { Component, ViewChild } from '@angular/core';
import { NavController, Navbar } from 'ionic-angular';

Get a reference to the navbar
@ViewChild(Navbar) navBar: Navbar;

On page enter, replace the back button function

ionViewDidLoad() {
    this.navBar.backButtonClick = () => {
      // you can set a full custom history here if you want 
        let pages = [
			page: HomePage
