Cite author(year)[1] using one command BibLatex

Question

I am using following commands and macros to create a new citation style citation \aytcite which give out citations as "Author et al (2018)". So can we modify it and make it do "Author et al (2018)[2]" with the same \aytcite command?

\usepackage[backend=biber,style=ieee,sorting=none,labeldateparts,maxbibnames=99,maxcitenames=2,mincitenames=1]{biblatex} 
\ExecuteBibliographyOptions{
    url=false
}

\urlstyle{same}
\addbibresource{Biblio.bib}

My answer to Biblatex style=numeric: would like \textcite) style "Author et al., year [#bibliography]" only needs a few little tweaks to work with style=ieee

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=ieee, labeldateparts, backend=biber]{biblatex}
\addbibresource{biblatex-examples.bib}

\makeatletter
\newbibmacro*{simple:cite}{%
  \printtext[bibhyperref]{%
    \printfield{labelprefix}%
    \printfield{labelnumber}%
    \ifbool{bbx:subentry}
      {\printfield{entrysetcount}}
      {}}}

\newbibmacro*{textcite:init}{%
  \ifnumless{\value{multicitecount}}{2}
    {\global\boolfalse{cbx:parens}}
    {}%
  \global\undef\cbx@lasthash
  \global\undef\cbx@lastyear}

\renewbibmacro*{textcite}{%
   \ifboolexpr{test {\iffieldequals{namehash}{\cbx@lasthash}}
               and test {\iffieldequals{labelyear}{\cbx@lastyear}}}
    {\setunit{\multicitedelim}}
    {\ifnameundef{labelname}
       {\printfield[citetitle]{labeltitle}}
       {\printnames{labelname}}%
     \setunit*{\printdelim{nameyeardelim}}%
     \printlabeldate
     \setunit{\printdelim{namelabeldelim}}%
     \printtext{\bibopenbracket}\global\booltrue{cbx:parens}%

Alternatively, an extension of Obtain author name and year with a single citation command with ieee style in Biblatex could look like

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber, style=ieee, labeldateparts, sorting=nyvt, maxbibnames=99, maxcitenames=2, mincitenames=1]{biblatex}

\addbibresource{biblatex-examples.bib}

\DeclareFieldFormat{labeldate}{\mkbibparens{#1}}
\newbibmacro*{citenum}{%
  \printtext[labelnumberwidth]{%
    \printfield{labelprefix}%
    \printfield{labelnumber}%
    \ifbool{bbx:subentry}
      {\printfield{entrysetcount}}
      {}}}

\newbibmacro*{citeyear}{%
  \iffieldundef{shorthand}
    {\iffieldundef{labelyear}
       {\usebibmacro{cite:label}}
       {\usebibmacro{cite:labeldate+extradate}}}
    {\usebibmacro{cite:shorthand}}}

\newbibmacro*{aytcite}{%
  \ifnameundef{labelname}
    {\iffieldundef{shorthand}
       {\usebibmacro{cite:label}%
        \setunit{\printdelim{nonameyeardelim}}%
        \usebibmacro{cite:labeldate+extradate}}
       {\usebibmacro{cite:shorthand}}}
    {\printnames{labelname}%
     \setunit{\printdelim{nameyeardelim}}%
     \usebibmacro{citeyear}}%
  \setunit{\addspace}%
  \usebibmacro{citenum}}

\newbibmacro*{cite:shorthand}{%
  \printtext[bibhyperref]{\printfield{shorthand}}}

\newbibmacro*{cite:label}{%
  \iffieldundef{label}
    {\printtext[bibhyperref]{\printfield[citetitle]{labeltitle}}}
    {\printtext[bibhyperref]{\printfield{label}}}}

\newbibmacro*{cite:labeldate+extradate}{%
  \iffieldundef{labelyear}
    {}
    {\printtext[bibhyperref]{\printlabeldateextra}}}

\DeclareCiteCommand{\aytcite}
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{aytcite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}
