Spotlight Smart Lighting Battery operated Manual length

Just received these and am setting them up. I see the auto-shut off for up to 2 minutes. When I turn on manually in the app, I can see I can edit it for up to 15 minutes and have them stay on that long. Is there a way to make it longer than 15 minutes or is that the max? For example, if my kids are playing outside and I want the lights to stay on while they are playing for an hour, is that possible?Any way to set-up these for a schedule similar to the solar?Thanks.
