Pick-up-disabled item for certain heros?

[Mr.Christmas]

Is it possible to not allow a certain type of hero to pick up a certain item? (stop them before they pick it up, not allow them to pick itup then make them drop it)

Yes it is possible, let me just fetch a trigger from my RPG.

Edit:

Ok here it is:

Item wood totem
    Events
        Unit - A unit Acquires an item
    Conditions
        (Item-type of (Item being manipulated)) Equal to Boiled Wood Totem
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                Or - Any (Conditions) are true
                    Conditions
                        (Unit-type of (Triggering unit)) Not equal to Minotaur Hero
            Then - Actions
                Game - Display to (Player group((Owner of (Triggering unit)))) the text: |c0096FF96Your race...
                Hero - Drop (Item being manipulated) from (Triggering unit)
            Else - Actions
                Do nothing

This trigger will make sure that if any hero other than a 'Minotaur' hero picks up a certain item (in this case its a boiled wood totem) it will drop the item at the units feet and diplay a message.

is it possible to make the hero drop a no-drop item doing this?

For instance is there a way to do the check before the unit acquires the item? Like when the unit is issued the order to pick up something check if its picking up that certain item and if it is give the order to stop? How would I make this trigger?
