[mkgmap-dev] Too many POIs

Hi all, In my map build I am getting too many POIs at a location (I am merging some other data with the OSM data), so some of my POIs are being discarded. These POIs are not vital, but it would be nice to include them if possible. As each subdivision only allows 255 points, I wondered whether a new subdivision could be created when one fills up. I'm new to the structure of the Garmin format, so I'm not sure whether the number of subdivisions can be changed 'on the fly'. Has anyone any suggestions as to whether this is feasible or a non-starter? Thanks, Mike
