SaveToNcs_InitialShowUAA
Controls whether UAA controls are shown or hidden when the "Save to NCS" dialog is opened (requires SaveToNcsWithUAA=1). Its value has the following meaning:
0 – UAA elements are initially hidden.
1 – UAA elements are initially displayed.
any other value – UAA elements are initially shown if any of the involved clips has a non-empty “CreationID”

Independent of this parameter, the user can click a button to toggle UAA controls on/off.
Possible values: 0, 1, any other number
Default value: -1
