Adding Hata-Okumura and CrossWave Models in Atoll

Hello, I’m new to Atoll and would like some advice regarding propagation models. I noticed that the Hata-Okumura model and CrossWave aren’t available. How can I add these models to Atoll?

I’ve installed CrossWave, but all the tabs in the settings are disabled. I also need help setting up the Hata-Okumura model in Atoll. Any assistance would be appreciated!
