No problem, @kshitizshankar. 
I believe I see what you mean – yes, this can be done directly inside Postman!
There’s another thread which goes over this in pretty good detail. Basically, if you click on a folder or request on your docs page, then check your address bar, you’ll see the unique tag for it at the end of the URL.

You can also do the same thing with the Introduction section: [Intro Sections](#intro)
Check out the following docs site for a ton more examples on using Markdown in Postman:
