How to dynamically add a hotspot to current scene, and keep in that current scene only?

I have a xml with various scenes and hotspots. I currently have functionality to add hotspots dynamically. However, how can I have it so that my dynamically added hotspot stays in the scene I added it to, so that when I go to a different scene, I can't see the hotspot, but when I go back it's there again?

Sample action that I'm currently using:

<action name="addlocation">
		removelocation(get(location));
		removehotspot(get(location));
		addhotspot(get(location));
		set(hotspot[get(location)].url,/location.png);
		set(hotspot[get(location)].ath,get(view.hlookat));
		set(hotspot[get(location)].atv,get(view.vlookat));
		set(hotspot[get(location)].height,30);
		set(hotspot[get(location)].width,30);
		set(hotspot[get(location)].edge,center);


		js(addPoint(get(location), get(view.hlookat), get(view.vlookat)));
	</action>

Hey Andrey :)

I knew about keep false, which indeed does the trick with removing the hotspot when I change scene, however when I come back to the scene where I added it, it's also still disappeared (I want it to be kept, but only for that current scene).

Cheers,
