Command to collapse/expand all top level forms (named range in vscode)

Is it possible to add a command to toggle top level forms between expanded and collapsed as we can manually do in vscode?
While working with large files you aren't probably interested/focused in all functions and that makes vertical skrolling over the file very annoying. If you would be able to collapse all forms automatically then you could expand only the ones you want to.

Example:
Clicking on the down arrow next to the top level parenthesis will collapse entire form

if you collapse all the forms in the file it will look like:

Thanks in advance!

This used to not have API. But it could have changed since.
