You can set a hanging indent for your Footnote Text style and then add the following pair of macros to your Normal.dotm:

Sub InsertFootnote()
'Codefrom wordmvp.com, modified by Stefan Blom
ActiveDocument.Footnotes.Add Range:=Selection.Range

With Selection
.Paragraphs(1).Range.Font.Reset
.Paragraphs(1).Range.Characters(2) = ""
.InsertAfter "." & vbTab
.Collapse wdCollapseEnd
End With
ActiveWindow.ScrollIntoView Selection.Range

End Sub

Sub InsertFootnoteNow()
'Code from wordmvp.com, modified by Stefan Blom
ActiveDocument.Footnotes.Add Range:=Selection.Range

With Selection
.Paragraphs(1).Range.Font.Reset
.Paragraphs(1).Range.Characters(2) = ""
.InsertAfter "." & vbTab
.Collapse wdCollapseEnd
End With
ActiveWindow.ScrollIntoView Selection.Range
End Sub



The macros will override the built-in commands to add footnotes and run the code instead. They will apply to future footnotes that you create in Word.
