categorize internal notes on each task / project

Rui Guimarães

I have the v14 c.e.

I need to categorize each internal note, not the messages but just the internal notes.
I use the project as each client is a project, and inside of it each task is a "article" on our case "apparel"

So let's say, as an example, that the Client "NIK#" is the project, and the tasks are "t-shirt" "joggers" etc, inside each task our team inserts the comments, files etc, but I need to categorize that as "pattern comments" or "tech file comments" etc...
Is possible to do that ?

I already read that I need to create a module for categories, but as simple, is possible to use "tags" for that ?
