Can the gas tank be "burped"?

I've tried rocking. Doesn't help much. Instead, I fill slowly, and let the vapors gurgle out between pauses until I get fuel right to the filler neck (or somewhat close). I've learned to get it to the point where it doesn't spill, but it takes practice and a cooperative nozzle.

There's supposed to be a means of purging vapors into the intake manifold, however I question whether or not it works in the case of fillup.

I'm hoping rather that Toyota will release a "fix" (i.e. an updated filler nozzle) to remedy this so we don't have to manipulate the tank in various ways to get a complete fill.

On a different note, about a minute or two after I park, I hear some sort of "release", but that's followed by the hydraulic brake pump, so the release may not be fuel tank related.
