[Doggiebox] volume

Hello, I am completely new to this list and to doggiebox. I have a beginner's question: Can I, and if so how, alter the volume of single components of the drumkit, such as snare or bass, while editing a drum loop ? It would be very unpractical to do this in the drumkit editor window, as this would allow not an adjustment of volume referring to selected bars. Thanks in advance kyurai
