Feature Description

The mat-list-option currently has an @Input selected: boolean which is bound to the checkbox' selected status.
I would like that (de)selecting can also change the boolean in my typescript like follows:

<mat-selection-list>
    <mat-list-option [(selected)]="isChecked">Check me!</mat-list-option>
</mat-selection-list>

Is my option checked? {{ isChecked }}!

Use Case

This would allow me to bind the selected status to a boolean of the model I have bound to my component, instead of accessing the selection list. Because I have references to the models, from my main component.
