Some further questions when I using hololens2

[Hawkpool]

I'm building an app with a ton of models , its more like a scene rather than just controlling an object. I want to bind the scene with local Spatial anchors but it seems not possible , because I have too much models and lots of them need to add interaction(can not group them all). Because those models have real gps info,so I wander whether I could use them by send in user's real-time gps info by socket or somthing, I tried to manually update player controller's location, which works on pc but not work on headset. Also I tried to switch the level map in order to update objects location by clicking a button. I add start ARSisson and stop ARSission in every map' bp, sometimes they don's show up normally. But if I remove stop ARSission fuction, maps show up and objects location all base on app starting place instead of now user place. I want the map and the scene controll all rebuild and update form user's real-time location by click a button. Is that possible? Or Is there a better solution ? Pls let me know..
