Fusion Benefits - Submit 1094c data file for the corrected employees

We have submitted 1094C file to IRS and it was accepted with error. Now we have to upload 1094C file (replacement one) in correction mode, what will be the approach for the same.

Below is the questions and need some reference for the same:

1) We would like to submit 1094c only(replacement file) for the corrected records (approx. 1000) not for the entire population.

2) As our parent 1094c transmission status was "Accepted with Error" what could be the process to generate 1094c (replacement file) so that it will not rejected by IRS.

3) If we wanted to submit the 1094c for all employees (not for 1000 employees), What could be our approach for the same. How to generate the file? How it will refer to parent transmission file? What we need to pass in the parameter as the parent 1094c transmission status was "Accepted with Error"
