Help : Trying To Edit Units Hairstyles\Beards

[IberianVaelico]

Hi, anyone here knows how I can edit the choice of hairstyles and beards used within the units of each culture?

In SandBoxCore ModuleData folder there's the xml file named "sandboxcore_bodyproperties". Within it I was able to find the following :
<BodyProperty
        id="fighter_sturgia">
        <BodyPropertiesMin
            version="4"
            age="30.00"
            weight="0.3000"
            build="0.5000"
            key="00000400000002412110000001211010010411111010002221111001301101000064300306112000000000000000000000000000000000000000000000D00000" />
        <BodyPropertiesMax
            version="4"
            age="40.00"
            weight="0.4000"
            build="0.7000"
            key="0008F00C40003690FEFEEFFEBBBFFFFFFFFFFF979EF8FFFEFFFFFFEFFFEFFFFE08EEE0890EFFFFFF000000000000000000000000000000000000000077C89105" />
    </BodyProperty>

I take it that the "key" part is where the hair\beard\skin\etc is? But I have no idea what to do with it. So does anyone here with proper modding knowledge has figured this out and knows how to help me edit this?

I'd much appreciate it.
