How do I register my city PERMANENTLY?

First- a <diatribe> - ;-)
Every new computer (laptop, desktop, tablet) using either Windows or Linux that I install Stellarium on here has to have my local Astronomy Club's GPS added to it. And our town, Elgin Quebec, Canada.
It is important that "Quebec" be added, as there are at least two other Elgins in Canada that I know of- In Ontario and Nova Scotia, and perhaps others that I do not know of.
As well, there are several towns in the USA called "Elgin" - In Pennsylvania, in Ohio, in Texas, etc...
It would be nice if a field could be added, above "Country", refining the geo location in places such as North America, to further define the location- a State or Province,and perhaps even Australia, which has several territories, no doubt with towns of the same name.

OK, my question- how can I upload or register my location "permanently"-
  Elgin, Quebec, Canada N 45.004, W 74.243
on the supplied city data base?
Yes , we ARE right on the 45th parallel - the actual 45.00000 degrees is on my property, 200 Metres from the US border.
200 years ago, the geometers could not accurately measure the 45th parallel, and placed the concrete Canada-US border markers here afew hundred feet too far south.
  Anyhow it's handy for setting up equatorial declinations. 45 degrees!
