Default [Q] [MIUI] Torch (flashlight) stay on in lockscreen when activated

Is there a way to make the torch (flashlight) in the MIUI lockscreen stays on when activated while the home button pressed long 1x? Just like the one that is used in the CM7 rom?
I have the MIUI rom but the only thing is when i use it on my LG Optius 2x is not will stay on when i hold the home button in lockscreen it shuts off after 1 a second.

Many thanks!
