The custom duration is great, just not sure why I can’t select 6 hours for the wine tours that I’d like to book using this app..
Hi there, @Ryan_Madsen and welcome to the Community 
I see that you’ve also opened a support ticket and my colleague Danis has already reached out to you. As he mentioned, the custom duration can be set in minutes only, but it’s possible to create a custom code to show 6 hours duration.
Danis has forwarded your request to the devs and will keep you updated
