[mkgmap-dev] polygon to point?

hello list, I have a question about mkgmap. Is there a possibility to get the information of an area in OSM converted to a point on garmin? This would be very usefull for example to find Car parks or camp sites or buildings tagged for example with amenity=restaurant etc. in the garmin menue. If such a feature does not exist, would it be possible to implement it with few effort? The best algorithm would be to take the geometric middle of the polygon and place a point there. The User should be able to customize which garmin type this point gets based on the tags of the polygon. The polygon should also be able to get a polygon type if it was used to create such a point. Thanks Christoph
