I believe that there is, if you're willing to commit grievous sins and use currently undocumented and unstable features. In other words, yes, but you probably shouldn't.
Basically, if you use the method of getting the parent that hosts the field of a property wrapper described here (Property Wrappers enclosing self only work with reference types?), require the parent to conform to a protocol exposing an observable object that the parent is observing, and then grab a reference to that observable object at some point, you could trigger a notification on the observable object to update the view.
But that's an incredibly hacky solution.
