Popover without separate component file

Ionic 3 app: Is it possible to create a popover without passing in a component containing the menu? In other words, in this code…

 this.popoverController.create({
  component: popupComponent, // <-- Can this be replaced with variable containing the HTML?
 ...
})

is there a way to declare a local variable with the menu’s HTML and pass it as the ‘component’ parameter? Something like …

var menuHTML='<ion-list>
<ion-item>Edit</ion-item>
<ion-item>Log out</ion-item>';

this.popoverController.create({
  component: menuHTML
 ...
})

Thanks.
