Q:

How to highlight important pages in glossaries page number list

In some books, the keywords page not only has a list of pages the keyword was referenced, it also bold or emphasize page numbers where the keyword was defined or explained. How do I do that with acronym option in glossaries?
With the MWE attached, the glossary page gives:

Fft fast Fourier transform. 1–3

I would like something akin to:

Fft fast Fourier transform. 2, 1-3

or 1,2,3 or similar. The best idea is to have a user field say user6 with a user defined label link such that in the acronym definition:
\newacronym[sort=FFT,user6={\pageref{link:fft}}]{FFT}{\textsc{Fft}}{fast Fourier transform}

I presume it may be quite an undertaking? 
MWE:
\documentclass[11pt,a4paper]{article}
\usepackage[acronym,shortcuts]{glossaries} 
\newacronym[sort=FFT]{FFT}{\textsc{Fft}}{fast Fourier transform}
\makeglossaries

\begin{document}
\Ac{FFT} is widely used to compute Fourier transforms. For more information see p.\pageref{link:fft}
\newpage
\section{Fast Fourier Transform}\label{link:fft}
\Acf{FFT}, is a radix-2 algorithm implementing the discrete Fourier transform...........................................................%explanation
\newpage
\ac{FFT} %some other references
\newpage
\printglossary[type=\acronymtype]
\end{document}

A:

I think the simplest solution is to just use the format key at the principle reference. Like this:
\documentclass[11pt,a4paper]{article}
\usepackage{hyperref}
\usepackage[acronym,shortcuts]{glossaries} 
\newacronym[sort=FFT]{FFT}{\textsc{Fft}}{fast Fourier transform}
\makeglossaries

\begin{document}
\Ac{FFT} is widely used to compute Fourier transforms. For more
information see p.\pageref{link:fft}
\newpage
\section{Fast Fourier Transform}\label{link:fft}
\Acf[format=hyperbf]{FFT}, is a radix-2 algorithm implementing the discrete Fourier
transform...........................................................%explanation
\newpage
\ac{FFT} %some other references
\newpage
\printglossary[type=\acronymtype]
\end{document}
