Changing the affected node for Fill Them Up and SGO

[BearWithASword]

I just want to preface this by saying I'm completely clueless when it comes to scripting (which is what I'm assuming will be needed.)

 

What I'm wonder is how I could switch the node that gets increased (belly node) in pregnancy mods to the Pregnancy Belly slider. I've mucked with manually increasing it via bodyslide and racemenu but obviously that only works if I do it myself and doesn't have any correlation with mods. Like I said, I'm oblivious as to how I'd change the scripts so what I'm asking for is a short tutorial assuming you're trying to teach an actual monkey. And obviously I wouldn't be redistributing this without the previous owners permission, this is just for my own use. If that's a violation of any rules I was unaware about I apologize.
