Is it possible to use the timer or speedo and record video with multicam? Of course with HLT controlling the external cam.

I am having the same problem on a Galaxy S5. My video was taken with the phone.
I read through the thread but did not see an answer.
Does anyone have a fix? I also resorted to using RaceRender but would rather have the Laptimer overlay.
BTW, that is me in the blue Vette. I was out with Edge Addicts ...
