I want to automatically default some gl segment values in GL Journal integrator.

Hello, Has anyone successfully done this or can anyone point me in the right direction?

we have a gl account structure of 7 segments.  the last 4 segments are not currently being used and should always default to 0000 each.  The key flexfield does have the 0000 as default. 

When using the Journal Intergator wizard, the excel spreadsheet includes the 'account' at the line level.  Use must enter all 7 parts(segments).  Once the excel is created we can  modify excel to default the last 4 segments if the 3rd segment is not blank. However, I feel we should be able to tell oracle to either default these values to the '0000' that is defined in the key flexfields OR
