Compute derivative of a composed function leaving indicated some derivatives [closed]

Is there a way to define in Mathematica a generic differentiable function $g:\mathbb{R}^2\rightarrow \mathbb{R}$ in such a way that when it computes the derivatives of a composed function involving $g$ it leaves indicated the derivatives of $g$ instead of actually computing them?

I'll explain myself better with an example:

Suppose we have defined this "generic" $g:\mathbb{R}^2\rightarrow \mathbb{R}$ and we have defined $F:\mathbb{R}\rightarrow \mathbb{R}$, $F(x)=7Log[x]$. When given the command $D(F(g(x,y)),x)$ I would like to have the output $7\partial_x(g)/g$. Is it possible?
