Hey Pambos,
There is a trick that you could use.
You actually cannot set specific center and zoom for each category, but! when you createa menu link to the category -> instead of choosing to use the default center and zoom set in the settings you could choose to use the marker boundaries. In this case if you have hotspots in spain -> the map will automatically try to zoom on all hotspots in spain.
Then if you have another category with hotspots in France -> the map will try to zoom on them etc.
Regards,
Daniel
