Anyone figured out the PopupTooltip?

[DuckTyped]

I already know how to hook into the ItemToolTip.SetBagItem, however....

I'm trying to append information to the popuptooltips and I can't figure it out, I've tried all of the following and gotten no results:

	local f = PopupTooltip.SetBagItem
	PopupTooltip.SetWornItem = function(control, info1, info2, ...)
		f(control, info1, info2, ...)
		PH_AddToolTipInfo(control, info1, info2)
	end

	local f = PopupTooltip.SetLootItem
	PopupTooltip.SetLootItem = function(control, info1, info2, ...)
		f(control, info1, info2, ...)
		PH_AddToolTipInfo(control, info1, info2)
	end

	local f = PopupTooltip.SetSmithingMaterialItem
	PopupTooltip.SetSmithingMaterialItem = function(control, info1, info2, ...)
		f(control, info1, info2, ...)
		PH_AddToolTipInfo(control, info1, info2)
	end

	local f = PopupTooltip.SetStoreItem
	PopupTooltip.SetStoreItem = function(control, info1, info2, ...)
		f(control, info1, info2, ...)
		PH_AddToolTipInfo(control, info1, info2)
	end

	local f = PopupTooltip.SetTradeItem
	PopupTooltip.SetTradeItem = function(control, info1, info2, ...)
		f(control, info1, info2, ...)
		PH_AddToolTipInfo(control, info1, info2)
	end

Is this even possible?
