Hi Will. Yes the same function as that add new button - but in groups or spaces in context like the image below - which appears on profile submenu pages already, just below the submenus,. perhaps its not possible in groups.
Why not just add the block to those pages, makes life a lot easier. In my opinion, if you or anyone f*cking around with too much coding, it can be a nightmare when you perform any upgrades.
This is a group on my site, it's the timeline on that group.
