Bring back video+audio recording in fps override mode

[2blackbar]

I have old build which has very nice audio recording option, im using fps override to minimize rolling shutter ( low jello option) but in new version i cant do it as convenient cause sound is disabled when using fps override or i have to record it to separate wav, separate wav option doesnt record for me and error pops up maybe because of class6 card i dont know but it doesnt really work and having separate wav isnt that convenient.
Here is how it looked like in old version :

Here is link to that version , its for canon 550D :

Is it possible to bring that option back or there is something risky that could ruin the footage ?
At least it could be enabled if real fps set in canon menu is 25 and override fps is 25 too, or canon fps is 24 and override fps is 24 , this way footage has original canon fps and sound wont be out of sync so there is no reason to record sound separately.
