assign derivative to function in Maple

I have a situation in Maple, where a large expression is calculated. In that expression a derivative appears, say $$\frac{\partial}{\partial x} f(x,t)$$. I know the function $$\frac{\partial}{\partial x} f(x,t)$$ but I do not know the function f (and integrating makes the problem excessively difficult, it is not worth to explain the details). Here is my question: how can I get maple to replace $$\frac{\partial}{\partial x} f(x,t)$$ with my known function? A naive assignment such as $$\frac{\partial}{\partial x} f(x,t):= expression$$ does not work.

It is using the subs command https://www.maplesoft.com/support/help/Maple/view.aspx?path=subs

such as subs( $$\frac{\partial}{\partial x} f(x,t)$$=known function, expression)
