Call Blocking from the Ooma Business App

I have an urgent need to block certain callers from the Ooma app on my iPhone.
Currently i have to take a note about a number I want to block, and remember to log-in to the Ooma website and block that number when I’m in my office at my laptop.
I would much prefer to block those callers instantly from the Ooma app on my phone.
It may seem like a small and petty thing - until you experience the sheer number of harassing, spam, junk, and other such calls I have incoming on any given day.
