Dynamic Period Control (config for existing NON-DPC rate category)

Hello Experts,

We are planning to implement a DPC functionality, however, upon checking if we can reuse the existing rate category and only update the DPC value, it is not possible as the field is greyed out (in change mode). Does this mean that the idea here is to create a new rate cat and it's not possible to enable the DPC function on existing NON-DPC rate categories. Ideally, we want to avoid creating new rate cat as it has a lot of impact on existing reports and other functionalities.

Thanks,
