On my Everspring Flood light I changed the Generic IO device (Parent device) with the On/Off buttons on it, to a Binary Light device not a motion sensor device.
I created myself an additional virtual motion sensor device and linked the tripped variable of the parent device to the tripped variable of the virtual motion sensor device, via some Lua code in the Lua startup.
Or as you said if you don’t want to use that code in LUA startup you can probably do it in Reactor rules instead.
Your trigger would be that the tripped variable on the parent device has changed to a value of 1 and your action would be to set the tripped variable on the virtual motion sensor to 1.
And you would need to do the reverse also, so when the parent device tripped variable changes back to 0 then you’d need an action to set the tripped variable on the virtual motion sensor device to 0 also.
