Is it possible to make endless loop virtual tour presentation?

just make an loop with actions, going from 1 panorama to another, then finally back to the first again.
nextpanorama_1.xml

<events onpreviewcomplete="starttour()" />
<action name="starttour">
lookto(90,10,45);
lookto(45,10,45);
loadpano(nextpanorama_2.xml);
</action>

nextpanorama_2.xml

<events onpreviewcomplete="starttour()" />
<action name="starttour">
lookto(90,10,45);
lookto(45,10,45);
loadpano(nextpanorama_1.xml);
</action>

This is quick and sloppy. But the onpreviewcomplete event, fires starttour, every time it's done loading. It will look around, and then load the next panorama you define. There are tons of other methods to get the effect desired (like turning on autorotate, define a timer (in xml, flash, javascript) that ticks down from 60sec and then load the next panorama)
