Dynamic accordion menu, with pages listed inside

Hello.
I’m having issues figuring out if what im trying to do is even possible within Webflows limitations.
I want to create a dynamic accordion in the sidebar of a site im designing.
The accordion should list a collection of categories, and inside each said category, i want to list the pages that have that category.

I would really like the list of categories to dynamically expand as more are created, and that they dynamically list pages of that new category inside.

Like so:

Cat1>
>> page
>> page
>> page
Cat2>
>> page
>> page
Cat3>
>> page
>> page
>> page
>> page
>> page

I can do it if I make the accordion panes static, and then only list the pages inside dynamically. But then i’ll have to create a new pane manually every time the clients creates a new category, which it not very practical.

Am I missing something, or is this impossible until nested collections lists are possible.

Best Regards!
