Make shutterlag set-able and make the flash fire before

[avipami]

Hello!!!
I Love the ML for the 5d  mIII and I have a question !

Is it possible that someone can incorporate a shutter lag setting ? 
I want the shutter to lag but not the flash firing
In other words I want the flash to go off when pressing the button, before the shutter by some milli seconds.
Maybe make it set-able by miliseconds?
Would help a lot !

Hello,

I have had from a long time, a similar desire for having a shutter lag setting.
I use it my camera also to shoot with a homemade trigger and
I really love to have the possibility to specify a time amount (in millisecond) after full-press before the camera take pics
Without that setup many shooting conditions (with triggers) are very challenging.

Thank you.

May I ask why?
Just curious to know when can that be useful, thanks.

For my cases (simple shutter delay) is because I can only setup trigger in advance of the exact time of shoot.

You can think as example a free falling object with camera at the ground and trigger sensor at half height.
The only way you have to adjust the exact shoot time is changing the height of sensor and this it can be difficult and time-spending.

Maybe some high-end trigger have this feature included but not the custom homemade





I think (tell me if I'm wrong) is not a very difficult, could some developers help me?
