(glossaries) grouping symbols according to the sections under headings

Question

For glossaries package, I would like to group symbols according to the sections they first appeared in under the heading of the section name. Firstly, my code reads as follows:

\documentclass[11pt,a4paper]{report}
\usepackage{amsmath,amsfonts,amssymb,amsthm,blindtext,epsfig,epstopdf,titling,url,array,xspace}
\usepackage[a4paper,bindingoffset=0.2in,left=1in,right=1in,top=1in,bottom=1in,footskip=.25in]{geometry}
\usepackage[nopostdot,style=super,toc]{glossaries}

\newglossary{symbols}{sym}{sbl}{List of Abbreviations and Symbols}
\newglossaryentry{aa}{type=symbols,name={aa},sort=aa,description={This is aa}}
\newglossaryentry{ab}{type=symbols,name={ab},sort=ab,description={This is ab}}
\newglossaryentry{ba}{type=symbols,name={ba},sort=ba,description={This is ba}}
\newglossaryentry{bb}{type=symbols,name={bb},sort=bb,description={This is bb}}
\newglossaryentry{ea}{type=symbols,name={ea},sort=ea,description={This is ea}}
\newglossaryentry{eb}{type=symbols,name={eb},sort=eb,description={This is eb}}
\newglossaryentry{fa}{type=symbols,name={fa},sort=fa,description={This is fa}}
\newglossaryentry{fb}{type=symbols,name={fb},sort=fb,description={This is fb}}
\makeglossary

\begin{document}
\tableofcontents
\printglossaries

\part{one}
\chapter{first}
\section{a}
\gls{aa},\gls{ab}
\gls{ea},\gls{eb}
\section{b}
\gls{ba},\gls{bb},\gls{aa}
\gls{fa},\gls{fb},\gls{ab}
\end{document}

The nomenclature prints as follows:

It seems the symbols are alphabetically grouped, but I would like to group them according to the sections they first appeared in under the heading of the section name (i.e. aa,ab,ea,eb are grouped under the title "a" and ba,bb,fa,fb are grouped under the title "b"). I spent so many hours trying to read the documentation but am struggling. Any help would be greatly appreciated. Thank you.
