Port location (unlocode)

[alru]

we have a problem with some Ports in our Analytics where we use qlik open maps

for example when customer is using Port Limetree / https://shipnext.com/port/limetree-bay-vilib-vir

it has the UN Locode VILIB which with automated layer enabled ends up in Russia:

When we use the same port with Auto detect and Names instead of un Locode we are getting the Country right but not the Port because its not referenced in your Database for Open Maps

which means that the country is recognised but not the PORT

Below you can find the latest up to date un Locode list question is, do you need to maintain this or can we also create our own reference as well ? 

Since you have listed Airports and addition of Ports would be very helpful here so we can show all of our Ports correct in our Analytical solution for our customers.
