Is there an easier way to get numbers in $\num{}$ to be in the same font as normal text than using $\text{\num{}}$?

```
\documentclass[varwidth]{standalone}

\usepackage[sfdefault]{overlock}
\usepackage[detect-all]{siunitx}

\begin{document}

num in maths mode: $\num{1200}$

num in text in maths mode: $\text{\num{1200}}$

\end{document}

```

I am using pdflatex and I want all the numbers in maths mode to be in overlock font, so they are consistent with the rest of the document.
