Using AddToSubscriptionFolderCmd

System

I am trying to use the AddToSubscriptionFolderCmd and everything seems to work as expected, except I cannot prefile the Name field when the dialog appears. The API documentation doesn't seem to reference a context item for this value. I would like to default it to the name of the workspace selected.

Sample Code:
Set iCmd = New IMANEXT2Lib.AddToSubscriptionFolderCmd
Set iContextItems = New IMANEXTLib.ContextItems

iContextItems.Add "SeletedFolderObject", iWS
iContextItems.Add "SelectedIManSession", iSession
iContextItems.Add "SelectedPageFolderObject", iWS
iContextItems.Add "IManExt.ShowReadWriteFoldersOnly", True

iCmd.Initialize iContextItems
iCmd.Update
iCmd.Execute


Where iWS is a valid iManage.ImanWorkspace object
