Allow Light in a Group to ONLY Turn On via its Own Motion Detection?

Do I understand this correctly? There is no way to prevent a light in a group from coming on during a motion event on one of the **OTHER** lights in that group without entirely disabling that light's motion detection?I have two wired floodlights and a battery step light in a group. The desired behavior is that I want to control all three devices, as a group, in the app and via Alexa. However, I do **NOT** want my floodlights, when turned on by motion, to turn on my battery step light. I want my step light to turn on when **it** detects motion itself, though."Which devices should detect motion in *Group*: When the devices you select detect motion, all lights in this group will turn on" is in the Group Motion Control menu. If I deselect my step light here, it disables **ALL** motion detection for the step light. Again, I would like to have the step light **NOT** be turned on by motion detected by other devices and only be turned on by its own motion detection.Am I missing something somewhere? Thanks, in advance!
