Mograph grid array size parameter

Hello

I notice that I spend a lot of time trying to get a good balance between the Mograph Cloner/Grid Array Count parameter and the size parameter. 
I’m wondering if there is a way to have the size adapt to the count so that if you add more clones, you don’t have to manually change the count. 
A looooong time ago I watched a tutorial on something unrelated and there was a coffee script the author used to do this, but I have no idea what that was…

Thanks!
