I remember seeing this on the USPS website a while back, but I haven't tried it myself yet.

I haven't been able to find a way to try this. I'm not sure that it exists yet, at least not everywhere. Seems like each year someone posts something saying that it may be coming, but I personally haven't seen it yet.
