Add 'Team Templates' to Primary Navigation Menu

I would like an area right below “My Tasks” and “Inbox” where I have a link for “Team Templates”. I would like to be an Admin for my team’s Template and have a distinct area where I can manage all of our standard task and project templates. I’d like to manage all of our Standard Operating Procedures (SOP’s) and Standard Templates from one place - so that it’s clear what steps are involved for anyone doing a certain process - like launching a new website, on all the steps I’d like to outline to make sure it’s “done done” (according to what I would call “done”). Thank you.
