How many providers do you have?  Unless you're really abusing ambients, it really shouldn't be very many.  If you really wanted to, you could create your own `PreviewProvider` that wraps all of them up into a single provider, but I wouldn't recommend it because it makes your previews less free-standing.

One of the points of Preview functions is that they show how to use the widget, including which dependencies that widget needs.  The fact they are free-standing with no implicit values provided is very much a feature, not a bug.
