Is configuration available to exempt an organization from DE FMLI taxes at a level higher than TRU?

Oracle Fusion Global Payroll Cloud Service

We have a small number of Delaware-based employees working remotely from home. Due to our low employee count in Delaware, we qualify for an exemption from the FMLI taxes. While there is existing documentation on how to set this exemption at the TRU level, our numerous TRUs and the possibility of new hires into these TRUs at any time poses a challenge. Therefore, we are seeking a way to set this exemption at a higher organizational level.

Alternatively, our business counterparts have suggested applying the exemption at the TRU level for each of our TRUs to ensure that any new employees are not inadvertently taxed. However, there is concern that this approach may negatively impact payroll calculation performance by adding the FLI and exemption values to each of our many TRUs.
