Extension of %ROWTYPE variable

Question

Hi all,
Really scratching my head with this one and I'm sure there's a very simple solution.
Reading values into a record which is based upon a system view called v$logmnr_contents
input_rec v$logmnr_contents%ROWTYPE;
I want an output_rec which is based upon this definition but has and extra column called IDX as the first column,
this would be of type NUMBER.
First question, is there a way to use the definition v$logmnr_contents but add this extra column?
Along the lines of...
Declare
v_idx number;
output_rec v_idx, v$logmnr_contents%ROWTYPE;
Also how would I copy input_rec to output_rec without specifying the individual fields in the record?
Hope somone has a solution.
Regards
Dave
PS - This is Oracle 9i if that makes any difference.

Thanks for all the replies.
I've included the procedure below in case anyone else in the future needs to know how to do this.
Thanks
