Void sim object return suggestion

Is there anyway to have the void sims only return an object if the owner leaves the sim? Have it start a timer after the avatar leaves the sim, if the avatar returns reset the timer.

Sometimes I like to fly my vehicles around in there and set down on one of the islands and sit and relax(and sometimes tweak the scripts of my vehicle) in the high FPS goodness of the void area. It's annoying that it returns objects after 5 minutes, but at the same time I understand this is done to keep the void sims clean of objects.

Not a huge problem, but it'd be nice for us recluses.
