Expressions controller logic editor

Is it possible to have two expressions in one expression controller? like to test for does " x = 5 " and " y = 20 " in the same controller. if there is a way to do that or another way please tell me

For example an expression like:

(trigger or A) and ENGAGED and not APPR


A is a keyboard sensor named A
ENGAGED and APPR are property sensors
trigger is a joystick sensor

is acceptable.

Have a look at the blender wiki
