Oh... OK... so, it's good that there is the same standard and service reference codes. But that depends on chocholousek , whether he will create picones for the USA as well. He already has a lot to do :-/. Maybe a donation would be useful or someone who can donate Chocholousk for his work, for example from the USA :-).
However, I can't really say... that what and how. Making picons is Chocholousk's hard work. You have to contact him and he will tell you himself... whether he has free time, willingness, resources for service reference codes, ... etc. ... for the creation and care of other picons :-/.
OK, hopefully he is reading the post and come forward with requirements/ suggestions. Thanks
