Pass array as List to ParamArray

I want to pass values from an array to a function with a ParamArray in the same way as if I had passed each value from the array seperately.

Simplified example to further explain my question:

Sub DoSomething()
    Dim MyArray(3) As Variant
    MyArray(0) = "A"
    MyArray(1) = "Whatever"
    MyArray(2) = 2
    MyArray(3) = "xyz"

    'Now I want this...
    SomeNativeFunction MyArray

    '...to act the same way like this:
    SomeNativeFunction MyArray(0), MyArray(1), MyArray(2), MyArray(3)

    '... because at this point I don't know how many elements MyArray actually might contain during runtime, so my only chance by now is something like this:
    Select UBound(MyArray)
        Case 1
            SomeNativeFunction MyArray(0)
        Case 2
            SomeNativeFunction MyArray(0), MyArray(1)
        Case 3
            SomeNativeFunction MyArray(0), MyArray(1), MyArray(2)
        Case .....
        Case 99999
            SomeNativeFunction MyArray(0), MyArray(1), MyArray(2), MyArray(...)
    End Select
End Sub

Function SomeNativeFunction (ParamArray args() As Variant)
    'can't touch this...
End Function

The way I call SomeNativeFunction in the example above at first MyArray will be handed over to position 0 in args, so args(0) = MyArray. But Instead, I need args(0) = MyArray(0), args(1) = MyArray(1), etc.. like I did in the second function call. The problem is, MyArray could have a different amount of parameters so hardcoding this would actually not work in all cases or at least would become really messy.

The subs/functions I want to call this way are given by Excel or other sources so changing them is not possible.
