Excel Multicolumn Listboxes. How to manually add additional data before data is inserted

I populate a multicolumn listbox with data from an array.
However, I would like to add one or two additional values manually before the array is populated that will appear at the top.

This is how I populate the listbox

With Me.lstContracts
.ColumnCount = 4
.ColumnWidths = "40,150;100,100"

    If arrContracts(x, colRecyclingContractCustomerID) = CustomerID Then
            .AddItem
            .List(.ListCount - 1, 0) = arrContracts(x, 1)
            .List(.ListCount - 1, 1) = arrContracts(x, colRecyclingContractSubscriptionName)
            .List(.ListCount - 1, 2) = arrContracts(x, colRecyclingContractFirstPickup)
            .List(.ListCount - 1, 3) = arrContracts(x, colRecyclingContractLastPickup)
    
    End If

End With
Next x

Select allOpen in new window

I understand that .addItem has an optional parameter that would allow me to specify the index but it looks like this only works in single column listboxes - not in multi like mine.
I would like to add a value 0 and/or 1

Any ideas how to solve this?

Thanks
