Hi Brodie, 

If you want to create your own programs and turn off smart zone feature and rain delay feature, go to Settings->Zones->Smart Zone and toggle the enable button for this certain zone. When the smart zone is disabled, the system will strictly follow the user program to water this zone and you can still keep smart zone feature for the rest zones. 

For more information about Netro smart watering,  here is an article about Netro three watering modes which might be helpful. https://netrohome.com/forum/posts/111

Thanks,
