Is it possible to have TOC include some headings from the md file?

[stratus-ss]

Let's say I have a summary file like this

- [Installing The Operators](rhoai_installing_operators.md)
    - [Installing The NVIDIA GPU Operator](blank.md)
        - [NVIDIA Cluster Monitoring](nvidia_cluster_monitoring_cli.md)

Inside Cluster Monitoring I have 3 different headings in the file itself:

## Enabling Monitoring Dashboard

<stuff> ...

## Enabling The NVIDIA GPU Operator Dashboard

<stuff> ...

## Using NVIDIA SMI

<stuff> ...

The headings work exactly as I expect when stitchmd does it's thing. In wiki software you can do things like include a maximum depth included in the TOC so that you can say have an H3 be included by not H4 +.

I know I could break these sections into their own file and include those in the summary to accomplish the same. But instead of having to break up files into tiny ones, I was wondering if it is possible to do the above? You can see my doc example here

I'd like to see:

* Installing The Operators
  * Installing the NVIDIA GPU Operator
    * NVIDIA Cluster Monitoring
      * Enabling Monitoring Dashboard
      * Enabling The NVIDIA GPU Operator Dashboard
      * Using NVIDIA SMI

In the TOC
