manually codec selection for RTC

As i am using RTC (SDK) with C#. I found a bit problem with its default codec selection. As the best codec and the frame size will be selected for different conditions. The changes will happen dynamically during the call. But i want to do it manually i want to select my own codec among the available and supported codec list. So is it possible to do so if yes than how?
