Improving FILE_EXISTS code

[NiGHTMARE]

Any advice on how I could condense the following code into something a bit shorter and sweeter?

 

ACTION_IF NOT FILE_EXISTS ~SPWI109.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI109.spl~
END ELSE BEGIN
ACTION_IF NOT FILE_EXISTS ~SPWI121.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI121.spl~
END ELSE BEGIN
ACTION_IF NOT FILE_EXISTS ~SPWI122.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI122.spl~
END ELSE BEGIN
ACTION_IF NOT FILE_EXISTS ~SPWI126.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI126.spl~
END ELSE BEGIN
ACTION_IF NOT FILE_EXISTS ~SPWI127.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI127.spl~
END ELSE BEGIN
ACTION_IF NOT FILE_EXISTS ~SPWI128.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI128.spl~
END ELSE BEGIN
ACTION_IF NOT FILE_EXISTS ~SPWI129.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI129.spl~
END ELSE BEGIN
ACTION_IF NOT FILE_EXISTS ~SPWI130.spl~ THEN BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/SPWI130.spl~
END ELSE BEGIN
 COPY   ~LoI/spells/NMWI101.spl~ ~override/NMWI101.spl~
END
