Acronyms that include other acronyms (acro package)

Question

I am using some acronyms that include some other acronyms (e.g., MRI and structural MRI) (acro package). I would like the output to be:

List of abbreviations

MRI magnetic resonance imaging

sMRI structural MRI

and within the text:

Magnetic resonance imaging (MRI) and structural MRI (sMRI); sMRI and MRI.

Instead, I am getting something ugly:

As you can see, the 'MRI' acronym gets introduced in the List of abbreviations and therefore is not defined at first usage in the text. I am aware of this post, but the solution didn't work for me, probably because I am using a different package.

Your help is greatly appreciated!

MWE:

\documentclass[paper=a4, fontsize=12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{pdfpages}
\usepackage{acro}
\DeclareAcronym{mri}{
  short = MRI,
  long  = magnetic resonance imaging,
  tag   = abbrev
}
\DeclareAcronym{smri}{
  short = sMRI,
  long  = structural \ac{mri},
  tag   = abbrev
}
\begin{document}
\printacronyms[name=List of abbreviations]\markboth{List of abbreviations}{List of abbreviations}
\Ac{mri} and \ac{smri}; \ac{smri} and \ac{mri}.
\end{document}

Answer 1

You can use the list key. Notice though that this might give unpleasant results if smri is used before the first time mri is used in the text.

\documentclass[paper=a4, fontsize=12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{pdfpages}
\usepackage{acro}
\DeclareAcronym{mri}{
  short = MRI,
  long  = magnetic resonance imaging,
  tag   = abbrev
}
\DeclareAcronym{smri}{
  short = sMRI,
  long  = structural \ac{mri},
  list  = structural \acs*{mri},
  tag   = abbrev
}
\begin{document}
\printacronyms[name=List of abbreviations]\markboth{List of abbreviations}{List of abbreviations}
\Ac{mri} and \ac{smri}; \ac{smri} and \ac{mri}.
\end{document}
