Requesting New Airports?

[newbie here]

In my current location, the nearest airport is actually ‘CJA3’ (Morden, Manitoba, Canada), but my stats page shows it as ‘KPMB’ (Pembina, North Dakota, USA). My assumption is that this is simply due to CJA3 being missing from the FlightAware databases. Is this the proper forum for me to request that it be added? If and when it is added, would I need to change anything on my side? Right now the ‘Click here to change’ doesn’t do anything.
