Recommended approach for multiple rates paid out in the same pay element for an absence plan.

We need the recommended approach on how to approach a business requirement for the following scenario -
Currently we have an Absence plan for Vacation in the US. This plan caters to multiple states. Out of all the states in this plan, one of them needs to be paid out at a different rate than the others. To achieve this, we have used the rate definition in absence entries and balances section.

Now we have a requirement for more cities/states needing to be paid out at this rate.
The issue we are facing is that there is only one element that can be attached to an absence plan for all payments.
