How to Add DocType in Workspace (left side Panel) as a sub Workspace

I Want to Add Lead DocType under the CRM workspace as a sub workspace…
means I want to access Lead Doctype directly from a left side panel…

Thanks in Advance

Having a hierarchy is not out-of-the-box in v13 available. There will be sth. similar as you can see in frappe wiki navigation, that has been announced to be part of v14 (and might cover your requirements).

Ok Thanks, I will check.
