I have a certain set of equations in my document which I would prefer cleverref to reference using a different noun. That is, for some equations I would like cleverref to reference those equations as usual, e.g., Equation 1. However, for a specific set of equations I would like cleverref to reference them as Rule 1.
MWE
\documentclass{article}
\usepackage{amsmath}
\usepackage{cleveref}
\begin{document}
\begin{equation}\tag{I-EQ}
\label{eq:1}
a + b
\end{equation}
\begin{equation}
\label{eq:2}
c + d
\end{equation}
Reference \Cref{eq:1}.
Reference \Cref{eq:2}.
\end{document}
In the above example, I would like eq:1 to be referenced as 'Rule (I-EQ)', while eq:2 continues to be referenced as 'Equation 1'.
