Smartthings Hub and Rachio Gen 1 Default Zone Runtime

I am using a Samsung Smartthings hub and and door sensor attached to with a water float sensio attached to determine when my pool water is getting low. I have a Rachio Gen 1 controller with one of the zones set to put water in my pool. I enabled the Rachio from within the Smartthings app and my zones are available, but it seems like all I can do in a routine is start a zone and it runs for 10 minutes by default. Is there anyway to change that default 10 min setting?
