Hi!
You can use some additional action
for example:
action name="hsOnclick"
copy(prevscene,xml.scene);
loadscene(%1);
/action
and in hotspot
onclick="hsOnclick(somescene1);"
or
style name="hsStyle" ..... onclick="hsOnclick(get(linkedscene));"
and
hotspot name="hs2" style="hsStyle" .... linkedscene="somescene1" .... /
hotspot name="hs3" style="hsStyle" .... linkedscene="somescene2" .... /
