Adding a dynamic menu to hotbox zone marking menu ..is it possible?

[kahwatikid]

Hi there,
I'm trying to add a list of my scene's perspective cameras to my hotbox. This has been a feature I've always wished Maya could have...and so I'm venturing down dark twisted roads....bleh.



I can get it to list out a menu, but I have to keep executing my script to update it.
I'd also love it if I could get it to show just below the existing Hotbox -Center zone's marking menu.

Not sure if you can add something dynamically created there...yes?no?maybe?help?

Here's what I have so far....I've taken code from maya scripts folder.

Any and all help is greatly appreciated!

Thanks

$panelz = `getPanel -withFocus`;
global proc buildPerspLookthruHBMenu( string $parent, string $panelz)
{
    $panelz = `getPanel -withFocus`;
    string $panelzType = `getPanel -to $panelz`;
    if ($panelzType == "modelPanel")
    {
        print $panelz;
        string $cameras[] = `listCameras -perspective`;
        string $Ocameras[] = `listCameras -orthographic`;
    
        // Rebuild menu
        //
    
        setParent -m $parent;
    
        menu -e -deleteAllItems $parent;
    
        python("from maya.app.stereo import stereoCameraRig");
        for ($camera in $cameras)
        {
     // Prune out any children of camera rigs. Non camera
     // rigs only have 1 camera.
     //
     int $isMono = python("stereoCameraRig.rigRoot('"+$camera+"') == ''");
     if ($isMono)
     {
     menuItem -l $camera -command
     ("lookThroughModelPanel "+$camera+" "+$panelz);
     }
     
        }
            python("from maya.app.stereo import stereoCameraRig");
        for ($Ocamera in $Ocameras)
        {
     // Prune out any children of camera rigs. Non camera
     // rigs only have 1 camera.
     //
     int $isMono = python("stereoCameraRig.rigRoot('"+$Ocamera+"') == ''");
     if ($isMono)
     {
     menuItem -l $Ocamera -command
     ("lookThroughModelPanel "+$Ocamera+" "+$panelz);
     }
     } 
    }     
}


buildPerspLookthruHBMenu("MayaWindow|HotboxCenter1", $panelz);
