Deserialiaze xml with same element but with different attributes and child elements

In the following code the tools that create automatically the xml parser classes always merge the fields:

<order>
<ItemType type="Clubs">
    <Club num="1">
        <ClubName>Some Name</ClubName>
        <ClubChoice>Something Else</ClubChoice>
    </Club>
</ItemType>
<ItemType type="Gift" val="MailGreeting">
    <GiftName>MailGreeting</GiftName>
    <GiftDescription></GiftDescription>
    <GiftQuanity>1</GiftQuanity>
</ItemType

What I would like to have is something like this:

[XmlRoot("order")]
public class Order
{
    [XmlElement("ItemType")]
    public ClubType WhateverInstance { get; set; }

    [XmlElement("ItemType")]
    public GiftType SomethingInstance { get; set; }
}
