Alabama Overtime

HCM 9.2 Image 046

I was reading more on AL overtime rule. As a company we give Overtime for hours worked (our hours worked includes holiday). I see they can only get the tax exemption on actual hours worked. Any idea how to create a Time and Labor rule for both, but would have to reduce the OT that fully tax. See example below.

For example. If the work week I actually work 42 hours plus there was 8 hours of holiday. As a company I should get OVT for full 10 hours but as AL I should only get 2 OVT hours that are exempt from taxes. If I create a Time and Labor rule is there a way to reduce the 10 to 8 and create AL OT for 2?
