one or more closed polygons inside( static obstacles )

[120ccz]

Hello.
I have a problem. I see that the field loaded in the demo only demonstrates a closed polygon. I also see that the field can be determined by loading the GML file or giving the coordinate value directly in the demo. If you consider that there are one or more closed polygons ( static obstacles ) inside, is the content of the warehouse supported ? If yes, what changes need to be made in the way of loading ?
Thanks !
