I think you should use the easiest way.
Create map for path2 with center where you want. Reassign map for path2 to it. Show map by simple call zhgooglemap.
Do the same for other paths.
And if you want to show all paths in one map - create map for it and show on it my category or groups.
but its not confortable. If I will have for example 30 paths, I have to create 30 maps with with singles maps and one map with group.
I dont know, why dosnt work to set up the last parametr in path for category or groups (placemark, path, all).
I need to check this plugin call. Probably, I didn't restrict (in case path) the other map objects (for example, placemarks) which belong to that map.
For example, you can call plugin with new map, and tell show only path. I think it will be shown, but your map center will not change to your placemark, because I change map center only in case I found this placemark.
I think I need to add one more parameter into plugin call - new map center, defined by latitude and longitude. In this case when you pass it, I'll change map center to it.
