Multi page title

Hello there I want to put one title for all of my app, right now I'm using this code in every single page:

<ion-view>
    <ion-nav-title>
        <img src="img/logo.png">
    </ion-nav-title>
    <ion-content>
        Test test
    </ion-content>
</ion-view>

I can use this one too:

<ion-view nav-title-custom-directive>
    <ion-content>
        Test test
    </ion-content>
</ion-view>

(and the directive would write the title)

But I don't like this methods. I want something that make this title in all of the app without changes...
Suggestions?

Thanks!
