Add fictitious subsections to RefTeX TOC

[Kourosh Kalayeh]

Hi Everyone,

I’m trying to add a "fictitious" subsubsection to the RefTeX TOC so that it appears in the RefTeX table of contents but does not render in the compiled document. For example, I’d like to add 2.3.1 General and 2.3.2 Aim 1 to the following TOC;

2.3 Approach
    2.3.0.1 Sub approach-1
    2.3.0.2 Sub approach-2
    2.3.0.3 Introduction
    2.3.0.4 Expected Results, Interpretations, Possible Pitfalls
    2.3.0.5 Statistical Plan

To get the following,

2.3 Approach
    2.3.1 General
        2.3.1.1 Sub approach-1
        2.3.1.2 Sub approach-2
    2.3.2 Aim 1
        2.3.2.2 Introduction
        2.3.2.2 Expected Results, Interpretations, Possible Pitfalls
        2.3.2.3 Statistical Plan

I have tried \phantomsection and \addcontentsline as below;

\phantomsection
\refstepcounter{subsubsection}
\addcontentsline{toc}{subsubsection}{Aim 1}

This works with \tableofcontents command in LaTeX but not with RefTeX.

Is there a straightforward way to achieve this in RefTeX?

Thank you for your help!

Best,
Kourosh
