How can I drive the volume of one file with the start of files in a random container?

Question

Hey everyone!

So I'm just coming back to Wwise after a couple years not using it at all. I'm creating various ambience zones for a project and in more forested areas I'd like to raise the volume of a looping "wind blowing through trees" file when a random container of wind gusts plays. I assume I'm going to be using an RTPC on the "wind blowing through trees" file that controls the voice volume, but how do I get the random container activations to drive the X-axis of that RTPC?

Also am I even going about this the right way?

Thanks,
