Is there a way to easily add large number of repetitve sound effects?

Hi, I've been searching about this for a long while but I find myself stuck.

I have an animation of a beating heart and a single sound effect sample of one heart beat. The heartbeat slows down and then speeds up at some point. I refuse to believe adding repetetive sound effects has to be done manually in this software.

Is there a quick way for me to add this sound effect to a track in specific, variable intervals? Is there a function for that? Or is there some sort of automation script I could find or make where I can just enter the list of timestamps and clip speed multipliers for the script to do it for me? Please help.

(This isn't the first time I encounter this challenge, last time I was supposed to animate a giant steam engine with variable speed and adding all the sound effects took so much time.)
