Hassio Automations GUI Issues - Missing a way to set "for:" for a triggered event

I am fairly new to hassio and I truly do love it. I keep getting frustrated along the way when trying to remain within the web GUI.

Current issue - when adding automations with a trigger there is no way to set the “for:” length. Seems like an easy field to add?

I want to be able to create an automation that alerts me if a door stays open for longer the 30 minutes. There is not a way to do this common task within the gui?
