Sound wave reference from sound cue

I’m a sound designer looking to try and do some in-game implementation of a sound re-design project using the Match3 demo game. I’ve managed to locate the section where most of the sounds are called in Grid_BP and I can successfully change the sound waves to different wave files. This means that I can implement a one-hit sound that will be unique and the sound will be re-designed.
However I want to use a sound cue for some of the sounds, for example the bombs which could be manipulated in pitch and intensity to create a more dramatic explosion depending on how much power the player has.

In the attached example, this is where the sound wave reference is called and converted to an array entry, then put into the ‘Move Effect’ array, which the game then plays back using some functions that go beyond my understanding!

I think what I’m trying to do here is take a sound cue and use it as a sound wave reference… but I can’t work out how to do it. Can I do this and what’s the best way of going about it?
