Overcoming CRTDUPOBJ limitation

Hi all

I'm trying to get round a limitation in CRTDUPOBJ as hopefully this 
scenario illustrates:

Library1 has physical files A and B, and logical files X and Y. 
Library2 has physical file C and logical Z. 
File X is a join logical over both physicals A and B. 
File Y is a logical over physical B.
File Z is a join logical over both physicals A and C.

I want to create a test environment (in Library3) with all these files. 

1) CRTDUPOBJ OBJ(A) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3) 
2) CRTDUPOBJ OBJ(B) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3) 
3) CRTDUPOBJ OBJ(C) FROMLIB(LIBRARY2) OBJTYPE(*FILE) TOLIB(LIBRARY3)
4) CRTDUPOBJ OBJ(X) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3) 
5) CRTDUPOBJ OBJ(Y) FROMLIB(LIBRARY1) OBJTYPE(*FILE) TOLIB(LIBRARY3)
6) CRTDUPOBJ OBJ(Z) FROMLIB(LIBRARY2) OBJTYPE(*FILE) TOLIB(LIBRARY3)

At V4R3M0 1) to 5) completed and 6) failed. At V4R4M0 6) now completes 
but logical Library3/Z points to Library1/A, not Library3/A. This is in 
keeping with the documentation, but I want Library3/Z to point to A & C 
in Library 3 (not much of a test environment otherwise ;-) ).

I've tried deleting and recreating (ADDLFM) the logical file member to 
point to the correct file, but it fails. A save/restore doesn't do the 
trick either. The only option I know that works is to recreate from the 
source. On our development box that isn't a problem, as we have the code 
for virtually all our software but it's a bit cumbersome. In a setting 
where the source member isn't available I can only think of creating one 
(from the the file APIs) and compiling against that. That seems even more 
contrived.

Can anyone point out a solution I've missed out (other than a better DB 
structure - I'm not able to do anything about that as yet :-( ). I'm 
after a generic solution I can include in my DBG/400 software for other 
people in the same situation - I guess I'll go with the create source 
method if I can't avoid it.
