Edit County Check database?

I habitually disable County Check because I want to use different standards in the way I write place names. But I see the value of having that check. So, I was wondering if I can edit the data used by County Check . Examples: I want to put Twp after a township name and Co after a county name (but not say County), and I want to use the standard postal abbreviations for Provinces in Canada and States in the USA, and I want to say USA not any other form of it, and I similarly want UK. Can I make these changes?

No. That has been a long sought enhancement.
