Amount changed pixels in the camera annotation ?

Hi,

Is there a way to see the amount of changed motion pixels and show the in the camera name(Annotation)?

I use external motion and the manual only describes the internal motion, so %c and %f do not work..... The version that I use is RPi Cam Control v6.0.37

Perhaps it would be also nice for a user setting for change the position of this text. (left right up down in the camera picture)
