Does Google Org Chart support multiple "Manager" and mouseover event on <DIV> within a node?

[Wiggins Ching]

Hi, the Google Org Chart is nice but one of the requirement is to support multiple "Manager", can it do that? Moreover, can I have mouseover event on <DIV> within a node (with "allowHtml" set to "true")? I need to do so because in my organization, many staff having the same post (e.g. System Analysis), so I want to define several names within a node and when a user moving the cursor over one of the name, the photo of that staff will be shown. Thanks.
