Fields from unused record formats

I'm a bit stumped by this and hope someone in this group can point me at a way
to understand this.

Situation:

Given an externally described print file with multiple record formats.

for example:
FMTA
    FieldA1             Char    10
    FieldA2             Char    20
FMTB
   FieldA3             Char   15
FMTC
  FieldA1              Char   5
  FieldA2              Char   6
  FieldA3              Char   7

When I have an RPG/400 (RPG/III) program that uses this file and only uses
FMTA I get a clean compile and can use the program because although all
formats exist in the print file, only the fields from FMTA are brought into
the program.

But Now I have tried to convert ot RPG/IV and even though only FMTA is written
to in the program, all formats of the external print file have the fields
brought into the program.  I am getting a compile error:

RNF6033   Length of externally-described field is not the same as a 
 prior definition; specification is ignored.               

So after all this here is my question:

Is there some way to tell the RPG/IV compiler to ignore those record formats
of the print file which are not used?
