Adding `Initials` to margin?

[mrphilk]

Hi,

I create lengthy reports for work that will often require the attention of different people but only certain paragraphs will apply to them.

Can someone give me a way of adding an area / small colum to the left of a document that will allow me to initial certain areas so they know where they need to read.

This way the document can be easily circulated around the office and people dont need to keep reading what they dont need.

Thanks!
