Is it possible to create an IObservable from an Action listener?

I have a class that has an event defined as an Action<Guid>, as opposed to a classic EventHandler with EventArgs. Is there a way to convert this to an IObservable the same way would be done with a standard EventHandler? I need to do this so I can merge with other IObservables.

If you have this class:

public class Foo
{
    public event Action<Guid> Guid;
}

Then this is the code you need to turn the non-standard event into an IObservable<Guid>:

var foo = new Foo();

var guids = Observable.FromEvent<Guid>(
    h => foo.Guid += h,
    h => foo.Guid -= h);
