Add plural to newdualentry from LaTeX/Glossary

Question

LaTeX/Glossary suggets the following command for combining a glossary entry and an acryonym:

\usepackage{xparse}
\DeclareDocumentCommand{\newdualentry}{ O{} O{} m m m m } {
  \newglossaryentry{gls-#3}{name={#5},text={#5\glsadd{#3}},
    description={#6},#1
  }
  \newacronym[see={[Glossary:]{gls-#3}},#2]{#3}{#4}{#5\glsadd{gls-#3}}
}

How can I add the plural to this command, so I can use \glspl{LED} showing LEDs? I know that appending a 's' is the default plural form, but I need a way to customize the plural. I tried the following with no luck

 \usepackage{xparse}
 \DeclareDocumentCommand{\newdualentry}{ O{} O{} m m m m m } {
     \newglossaryentry{gls-#3}{name={#5},text={#5\glsadd{#3}},
        description={#6},plural={#7},#1
      }
      \newacronym[see={[Glossary:]{gls-#3}},#2]{#3}{#4}{#5\glsadd{gls-#3}}
 }

Thanks!

This works for me (However, a 7-arg command is difficult to remember!):

\documentclass{article}


\usepackage{xparse}

\usepackage[acronym]{glossaries}


\DeclareDocumentCommand{\newdualentry}{O{}D<>{}m m m m m } {
  \newglossaryentry{gls-#3}{
    name={#5},
    text={#5\glsadd{gls-#3}},
    description={#6},
    plural={#7},
    #1
  }
  \newacronym[see={[Glossary:]{gls-#3}},#2]{#3}{#4}{#5\glsadd{gls-#3}}
}

\makeglossaries




\newdualentry{LED}{LED}{LED}{Light emitting diode}{LEDiodes}

\newdualentry{Ox}{Ox}{Ox}{male cow}{Oxen}


\begin{document}

Here is an entry: \gls{gls-LED} \glspl{gls-LED}

An some biology here: \gls{gls-Ox} \glspl{gls-Ox}

\printglossary[type=main]
\printglossary[type=acronym]

\end{document}

Edit Some notes on the design of the command about the optional arguments:

Say,you've got a small document like this

\documentclass{article}

\usepackage{xparse}

\DeclareDocumentCommand{\somecmd}{O{}O{}m}{%
Optional 1: #1

Optional 2: #2

mandatory: #3
}

\begin{document}

\somecmd[A][B]{C}

\somecmd[A]{C}

\somecmd[][B]{C}



\end{document}

1. The first call will assign A, B and C correctly to the relevant slots
2. The second call will use A for the 1st, C for the 3rd one --> the 2nd one is empty --> Is this correct? Yes and no, since it's not clear that A is meant for the 1st or the 2nd optional argument.
3. This call will explicitly leave the 1st one empty, the others are 'correct'

It's better to replace the 2nd optional argument style with D<>{} or similar tokens to make some difference. Or append the 2nd optional argument to the end of the list, being the 3rd argument here.

Thats an MWE of how I use it. (mostly in german)

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{hyperref} % optional
\usepackage[acronym,toc,shortcuts,xindy,section=section]{glossaries}
\makenoidxglossaries

\usepackage{xparse}


% #1 = optional newglossaryentry value
% #2 = optional newacronym parameter
% #3 = label
% #4 = short form
% #5 = short form plural
% #6 = long form
% #7 = long form plural
% #8 = description
\DeclareDocumentCommand{\newdualentry}{ O{} D<>{} m m m m m m } {
  \newglossaryentry{gls-#3}{
    name={#4},
    shortplural={#5},
    text={#4\glsadd{gls-#3}},
    longplural={#7},
    description={#8},
    sort={#4},
    #1
  }
  \newacronym[see={[Glossar:]{gls-#3}},#2,shortplural=#5,longplural=#7]{#3}{#4}{#6\glsadd{gls-#3}}
}

\newdualentry{abb} % label
{\textbf{abbreviation}} % abbreviation
{\textbf{abbreviation plural}} % abbreviation plural
{\textbf{long form}} % long form
{\textbf{long form plural}} % long form plural
{\textbf{The description is a very long text.
It explains everything you need to know}} % description


\begin{document}

\printnoidxglossary[title=List of Abbreviations, type=\acronymtype, style=altlist]

\clearpage
\section{Chapter One}

This is what the first use of a glossary entry looks like: \glsfirst{abb} by default.\\
This is what the first use of a glossary entry plural looks like: \glsfirstplural{abb} by default.\\


First gls call in my text: \gls{abb}.\\
Next gls call: \gls{abb}.\\
First glspl call in my text: \glspl{abb}.\\
Next glspl call: \glspl{abb}.\\

\clearpage
\printnoidxglossary[title=Glossary,style=altlist]

\end{document}

Without any modifications, use the optional parameters:

\newdualentry
[    plural={Light Emitting Diodes}]  % Glossary
[longplural={Light Emitting Diodes}   % Acronym
,shortplural={LEDs}]
{led}{LED}{Light Emitting Diode}{...}
