Add chapter + paragraph to figure numbering

[rwaaijman]

Description

Is it possible to add besides chapter also H2, H3, etc to the figure numbering. So it is clear to what paragraph a figure belongs to? So the second figure number would be 1.1.1.2 in # > ## > ###

for example:

 ---
title: "Example"
format: html
    
fig-cap-location: top
crossref: 
    chapters: true
    fig-title: Fig
    title-delim: "."

number-sections: true
number-depth: 3

execute: 
  echo: false
---

# Chapter
Example numbering figures (@fig-2)

## paragraph

```{r}
#| label: fig-1
#| fig-cap: cap

df <- data.frame(x = 1:10, y = 11:20)
plot(df$x,df$y)
```

# Chapter
## paragraph
### sub-paragraph
Preferably the Fig-number would be 2.1.1.1 (first figure in heading3)
```{r}
#| label: fig-2
#| fig-cap: This is a test

df <- data.frame(x = 1:10, y = 11:20)
plot(df$x,df$y)
```
