How can I exclude pending workers from the seniority dates calculation?

As per current config Seniority Dates Calculation includes Pending worker period too, but we only want to include the Employee worker type into seniority date calculation. I am aware about the seniority date filters available but we are unable to edit "Enterprise Seniority Date - Person Level - Migrate" and "Legal Employer Seniority Date-Work Relationship Level-Migrate" to add Employee as worker type filter to seniority date.

How we can achieve this request?

Thank you
