Using the physics package to take second derivatives with respect to primed coordinates

As it says in the title, I am attempting to write a second derivative such as the following

and ideally would use the shorthand derivative from the physics package which would be the following.

dv[2]{x'}{t'}

However, the returns a "Double superscript" error because of the prime in the denominator. Obviously, this can be avoided by writing it out explicitly with frac. However I was wondering if there was a simpler solution.

Cheers
