Multilanguage Placemarks

Hi there

Sorry I'm bringing back and old subject but I'm a bit confused.
My site is in English and Russian, I've installed both languages(frontend and backend), the plugin is enabled and I use the native Joomla 3.1 multilanguage plugin (no joomfish, no falang)

What I want to do (if possible) is to have a placemark with the title, let's say, "Acropolis of Athens".

So, when I am in the map page in the english language I want the placemark title to be "Acropolis of Athens" but when I switch language and go to russian, I want the placemark title to be "Афинский Акрополь"

Do I have to create a second map, duplicate all the placemarks and translate them or there is somewhere where I can put the titles of them for each language?

Thank you
Dimitris
