Modification in Seeded HCM Extract

Hello Experts,

We have a requirement to add SFTP delivery options to seeded Payslip and US Third Party Quarterly Tax Extract and US Third Party Periodic Tax Extract.

Is it advisable and ok to add delivery option to these Seeded extracts or is there some other process that is to be followed.
When we are trying to make a copy of the seeded extracts and add delivery options in them we are facing some issues possibly because of the parameter tags getting mismatched at the payroll flow.

Thanks,
Shobhit
