Expand/Collapse to Specific Level Keyboard Shortcut

This is somewhat similar to this thread but not exactly. Is there a way to collapse and expand the outline to specific levels? Maybe using Ctrl+{Level number} with Ctrl+0 being the equivalent of Collapse All.

Sorry, there’s nothing like that right now. You can only collapse or expand all levels.

I’d like to see this function! I use it all the time in iThoughtsX and it is a great way to keep an overview in longer documents.
