Set (temporary) SaveAs path

[grNadpa]

Cannot seem to set the path for Word 2016 SaveAs screen. The statement

MsgBox Options.DefaultFilePath(wdDocumentsPath)

displays the directory I want.
But, after executing

'source: based on https://wordmvp.com/FAQs/MacrosVBA/SetDefFilename.htm
'change properties
Dim dtToday As Date
  dtToday = Date
    If Documents.Count > 0 Then
         Set dlgProp = Dialogs(wdDialogFileSummaryInfo)
         ' Establish title
         dlgProp.Title =  "Waiver_" & dtToday & ".docx"
         ' Set the values
         dlgProp.Execute
         ' Show the dialog for testing purposes
         dlgProp.Show
    End If

The SaveAs dialog box shows up but with an entirely different path.

And with the bogus message

You don't currently have permission to access this folder

(It's the the path I last used to save a .docm document).

The keywords I use in this forum's search bring up how to change file names, but not directories.

I guess this ability qualifies merely as a "nice to have". But it really would be a nice-to-have.
