modern lists - group by more than 2 columns

Hi folks - we're using SharePoint online 365 modern. In a list view there we're only able to group by 2 levels of columns. We want to be able to group by more than 2 columns. I understand that out-of-the-box SharePoint does not have a way to group by more than 2, but I'm hoping there's a way we can use PowerShell to give us more than 2 levels of grouping... 

Does anyone know if this is possible using PowerShell?
