Generate two different outlines in an rmarkdown script

Hi!

I am writing a script in rmarkdown to generate a report with the outcome. As I am using rmarkdown syntax, when I open "Outline" sheet in RStudio I get the outline as it is going to be reported. I find this useful, but I would also like to be able to see an outline just for the code.

Imagine this is my rmarkdown script:

---
title: "Untitled"
author: "Me"
date: "`r Sys.Date()`"
output: html_document
---

# 1. Introduction

# 2. Results

<!---
# 1. Code 1 ----
--->

"```{r}"
somecode
"``` "


"```{r}"
someOthercode
"```" 

<!---
# 2. Code 2 ----
--->

"```{r}"
someOthercode2
"```" 


<!---
# 2. Code 3 ----
--->

"```{r}"
someOthercode3
"```" 

## 2.1 Variable A

<!---
## 3.1 Specific Code 3A
--->

"```{r}"
someOthercode3A
"```" 

## 2.2 Variable B 

<!---
## 3.1 Specific Code 3B
--->

"```{r}"
someOthercode3B
"```"

When I click in Outline cell in RStudio, I get the following outline:

1. Introduction
2. Results
    2.1 Variable A
    2.2 Variable B

Is there any way to indicate R that I want to interpret also another outline following R syntax, so, in the example before, I could get the following?:

1. Code 1
2. Code 2
3. Code 3
    3.1 Specific Code 3A
    3.2 Specific Code 3B
   

Thanks!

You should have an outline of the code chunk by there named label at the bottom of the source pane
