ReDim existing array with a second dimension?

I declared an array in my VBA function that has a dynamic size. As I cannot ReDim the first dimension of a two- or more-dimensional array, can I add a second dimension to a set array?

This is how I dynamically set the size of my array.

Dim nameArray() As String
Dim arrayCount As Long

For i = 1 To 100
    ReDim Preserve nameArray(1 to arrayCount)
    nameArray(arrayCount) = "Hello World"
    arrayCount = arrayCount + 1
Next i

Now I would like to add a second dimension.

ReDim Preserve nameArray(1 To arrayCount, 1 To 5)

doesn't work.

Is there a workaround?
