National Records, why are there not two categories?

So, Seems like I remember hearing that the rules had changed some years back, but why aren't there two categories of National soaring records? One category would be for flights that originate within the pilot's home country. The second would be for flights which originate in another country. For example, US National records set in Argentina... There will never be a level playing field in terms of the financial resources that can be brought to bear, but it's going to be a precious few that can afford to make the investment into trip(s) to Argentina or other remote locations. Rather than say only one or the other should be allowed, why not separate them into the two obvious categories? This rewards those who do make the additional effort to get to those locations and also preserves records for those who would attempt a task at home where the soaring conditions may not be the same?

Just pondering...
