Pin Comments in Zoho Desk

Pin Comments in Zoho Desk

Hello, 
I'm writing to ask if there is a way that we can add  a "pin" option to comments so that a "pinned" comment would show at the top of a ticket for review? Also would like to suggest if there could be a tab at the top section for "comments" section next to "Conversation" so that you could view all of the comments from the ticket in one place. 
Thank you!
