Clear SmartList selection from drop-down in Forms 2.0

Hello,

We have migrated to Forms 2.0, and are noticing that clearing a drop-down selection for a SmartList measure doesn't work the same way as Forms 1.0. While leaving the #Missing drop-down label in Forms 1.0 provides a blank space to select and clear out the selection, in Forms 2.0 that option isn't available. For now, we have to copy or drag an empty neighboring cell to clear out the selections, but wondering if it is possible to mimic 1.0's behavior. This poses a problem when all cells in the form are filled and no empty cells are available to clear an existing selection.
