Is it possible to call a function from a timeline?

I want to call a Construct 3 function from a timeline. The thing I'm trying to achieve is this:

I have a timeline which shows a series of sprites and other animations. At certain points in this timeline, I want to play an audio (which changes based on the sprite). I'm playing audio file in timeline directly right now which is like hardcoding the audio file. So, I need some way to reference different audio files here based on an input. Is it possible with timelines?

Give a keyframe a unique tag, and then use the Timeline Controller 'On keyframe reached' trigger to run some actions when the timeline reaches that keyframe.

Thanks. I'll try that. What I ended up doing was use a boolean instance variable, set it to true in the timeline where desired and have it trigger the function in eventsheet (with trigger once while true condition).
