Layered multi-touch containers touchthrough

There are multi-touch in DATs inside each containers(red&blue).

If I touch upper container(red), lower container is turned ON at the same time.
Is there a way to touch-select upper container(red) only ?

“clickthrough” has no affect on multi-touch in DAT.
I wanna know what should I do.

Sorry for my English.
