merging to scene

Hi,

I'd like to know how I can merge 2 scenes :

I've one scene in one xml :

<scene name="pano">


<plugin name="a1" ... />
<plugin name="a2" ... />


</scene>

and another xml with some additionnal parameters

<scene name="pano">


<plugin name="b1" ... />
<plugin name="b2" ... />


</scene>

I'd like to merge this 2 scene. Is there a way to do this ?

I tried loadpano(xml2.xml,null,MERGE), loadpano(xml2.xml,null,KEEPSCENES ) and loadpano(xml2.xml,null,KEEPSCENES|MERGE ) but it's not working

In other words, I'd like to make a loadinclude="", like if I have an <include url="" /> but dynamically, the path of the include is not known in the xml, it's passed dynamically through js

If you have any clue how to do that ... thanks !
