So I am addicted to Nailing down my custom functions and its cool but why oh why does Canon get shortsighted sometimes? I want Speedlight controls on my Custom Functions dang it! 
All my custom functions have everything else dialed in i am just explaining what flash settings below
CF1 Shoot with flash in normal lighting with bride hi speed sync flash if you end up outdoors 1/3 under exposed evaluative flash
CF2 shoot Receptions second curtain sync flash for light trails if i set the manual to slower shutter than regular speeds
CF3 no flash but use the flashes meter to pick up focus if needed when flash is still on the camera and turned on else all manual auto iso
I hope they come up with some updates that relate to that, why make it half baked??
Also, i want to be able to record all my functions to a card and transfer all the c1,c2,c3 functions to another 5dm3...I havent seen a way to do that unless i am missing something or is that a 1D only feature....because i have that on my 1DM3.
