Ion-title with description

Ionic Framework
#1

Hi, I have

  <ion-header>
    <ion-toolbar color="primary">
      <ion-title>Start Menu</ion-title>
    </ion-toolbar>
  </ion-header>

and would like to add a description under the title. How can I do this? Is it allowed to add another element but like?

  <ion-header>
    <ion-toolbar color="primary">
      <ion-title>Start Menu</ion-title>
      <ion-label> ... </ion-label>
    </ion-toolbar>
  </ion-header>
