XAML Go to visualState defined by binding

I don't have very much experience with XAML or expression blend yet. I am trying to make the initial visualState of my silverlight application be defined by a string binding.

So far, I am simply making a manual trigger for each possible visualstate:

<i:Interaction.Triggers>
    <ei:DataTrigger Binding="{Binding VisualState}" Value="DevOffline">
        <ei:GoToStateAction StateName="DevOffline"/>
    </ei:DataTrigger>
    <ei:DataTrigger Binding="{Binding VisualState}" Value="Public">
        <ei:GoToStateAction StateName="Public"/>
    </ei:DataTrigger>
    ....
</i:Interaction.Triggers>

It works, but I have 9 states in total, so I would like something universal like:

<goToStateAction StateName="{Binding VisualState}" />

Is it possible to do this? If so, where do I put it in my XAML? The same place?

The StateName property on the GoToStateAction behavior is a dependency property, so it seems like you should be able to bind to it. Just replace the DataTrigger with a PropertyChangedTrigger. It seems like you should be able to do the following:

<i:Interaction.Triggers>
    <ei:PropertyChangedTrigger Binding="{Binding VisualState}">
        <ei:GoToStateAction StateName="{Binding VisualState}"/>
    </ei:PropertyChangedTrigger >
</i:Interaction.Triggers>
