Requirements for trading station icon?

[Admiral Sausage]

I know how to build stations so they have wharf, shipyard, equipment dock, or defence platform icons, but what triggers the trading station icon? If I build a station with just storage and configure it to have some trade wares, it will automatically be named "trading station" but the icon remains the standard small factory icon. If I add an admin module it gets the defence platform icon but retains the "trading station" name. Is there something else I need to do, or is the icon simply not available to the player?

p.s. the typeface used for the icon is terrible. I'm pretty sure it's supposed to say "CR" for "credits", but it looks like "CA".

As far as I can tell, there isn't a way to get a trade station icon if your the player. I mean the game will give the station the title of "Trade Station" but the icon doesn't change so the game IS recognizing that it is a trade station.

Ideally, the player would be given control over what icon is used. Then we could choose what we want, including special icons like the pirate station.

+1 for the actual icon, this works for shipyards and wharves, doesn't it?
