Another treeview question - making only some items have checkboxes

[J3anyus]

I'm trying to create a treeview of parent and child objects, where only the child objects have checkboxes next to them. However, it seems like whether or not there are checkboxes is defined for the entire treeview with $TVS_CHECKBOXES, and I don't see any way to define it per-item. Here's what I have so far to create a basic treeview where everything has checkboxes and the parent items have a slightly different GUI style:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <TreeViewConstants.au3>

Local $mainTree, $treeitem2, $treesubitem1, $treesubitem2, $treesubitem3, $treesubitem4, $guiMsg
Local $mainTreeStyle = BitOR($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_CHECKBOXES)
Local $parentItemStyle = BitOR($GUI_EXPAND, $GUI_DEFBUTTON)

GUICreate("Treeview With Children", 400, 300)

$mainTree = GUICtrlCreateTreeView(2, 2, 396, 268, $mainTreeStyle, $WS_EX_CLIENTEDGE)

$treeitem1 = GUICtrlCreateTreeViewItem("Parent Item 1", $mainTree)
$treesubitem1 = GUICtrlCreateTreeViewItem("Child Item 1", $treeitem1)
$treesubitem2 = GUICtrlCreateTreeViewItem("Child Item 2", $treeitem1)
$treeitem2 = GUICtrlCreateTreeViewItem("Parent Item 2", $mainTree)
$treesubitem3 = GUICtrlCreateTreeViewItem("Child Item 1", $treeitem2)
$treesubitem4 = GUICtrlCreateTreeViewItem("Child Item 2", $treeitem2)

GUICtrlSetState($treeitem1, $parentItemStyle)
GUICtrlSetState($treeitem2, $parentItemStyle)

GUISetState()

Do
    $guiMsg = GUIGetMsg()
Until GUIGetMsg() = $GUI_EVENT_CLOSE
GUIDelete()

Is there a way to make it so the parent items don't have checkboxes but the child items do?

Thanks so much

Any ideas?
