Pinnacle 16 or 17 Volume on multiple clips at once?

[Bigotes]

Hello everyone
I introduce myself. I am Daniel from Argentina, a photographer, and addicted to video editing since pinnacle 8.
This is my first question.
As always with pinnacle, you can raise or lower the volume of a clip by placing control points or now called keyframes
My problem is that I don't know how to raise or lower the volume to a sequence of 10 or 15 clips simultaneously
Thank you in advance for the space provided.
Happy Easter
Daniel
