Db2 installation and configuration makes me complete information twice

[JAMOGRAD]

With BUILDJCL(COMPALL), we use the DEFAULT member to specify values for COBOL, CICS, Db2 and loadlib datasets.

INSTDB2 asks us to

//* Please change @DB2_HLQ@  
//*  (to the high level qualifiers of your
//* system's DB2 datasets (SDSNLOAD et cetera)
//* 
//* Please change @DB2_DSNTEP_PLAN@
//* to the name of the plan that was
//* used for the DSNTEP2 utility program
//*
//* Please change @DB2_DSNTEP_LOADLIB@ to
//* to the name of the load library
//* that contains the DSNTEP2 utility program
//*
//* Please change @DB2_SUBSYSTEM@ 
//* (to the name of your chosen DB2
//* subsystem (which must be running on the same MVS image as this
//* batch job) for example DBCG
//*
//* Please change @BANK_USER@ 
//* to the userid that will be accessing the
//* plan 
//*
//* Please change DSNV12DP to the appropriate value for your installation

DB2BIND asks us to

//* Please change @DB2_HLQ@  
//*  (to the high level qualifiers of your
//* system's DB2 datasets (SDSNLOAD et cetera)
//*
//* Please change @BANK_DBRMLIB@ 
//* (to the name you chose
//* for the DBRMLIB provided by Hursley Bank)
//*
//* Please change @DB2_SUBSYSTEM@ 
//* (to the name of your chosen DB2
//* subsystem (which must be running on the same MVS image as this
//* batch job) for example DBCG
//*
//* Please change @BANK_PACKAGE@ 
//* to the name you have chosen for the
//* package name in DB2, for example PHBANK.
//*
//* Please change @DB2_OWNER@ 
//* to the userid that will own the DB2
//* resources
//*
//* Please change @BANK_PLAN@ to 
//*  to the desired DB2 plan name
//* This must match the CSD and the Db2 Install job
//*
//* Please change @DB2_DSNTEP_PLAN@
//* to the name of the plan that was
//* used for the DSNTEP2 utility program
//*
//* Please change @DB2_DSNTEP_LOADLIB@ to
//* to the name of the load library
//* that contains the DSNTEP2 utility program
//*
//* Please change @BANK_USER@ to IBMUSER
//* to the userid that will be accessing the
//* plan

@DB2_HLQ@, @DB2_DSNTEP_PLAN@, @DB2_DSNTEP_LOADLIB@, @DB2_SUBSYSTEM@ and @BANK_USER@ are duplicated.

It's not the end of the world, but a little bit irritating.
