Is it possible to set up multiple mileage schedules for a single business group?

We have a requirement to create multiple mileage schedules for employees in the same business group and operating unit that doesn't require the end user to select the right option when creating an expense report .  It's for a group of people whose job titles are not unique and are not easy to group together.

Mileage expenses are claimed using Oracle Internet Expenses (Oracle version 12.1.3).

The mileage schedules we need to create are:

1. Schedule based on HMRC mileage rates and thresholds

2. Schedule based on a fixed mileage rate for people in receipt of a monthly car allowance payment

We currently have a single expense template and we pay mileage and expenses through Payroll instead of Accounts Payable.
