attach separate dnd_stop.vakata event to different selectors

[kpetrow]

I have multiple trees, one is a file browser that is available in multiple places/pages(gloabally available) and others are for a page specific feature. The dnd_stop.vakata stop handlers are different for these trees. Is there anyway to attach the handlers to the parent div's? or to add a selector on the "on" handler? none of these work:

$j(document).on('dnd_stop.vakata','#project_manager_body',function(){ })
$j('#project_manager_body').on('dnd_stop.vakata',function(){ })
