Adding new regions to a master

In Runway I've created around 50 pages based on a master, now I need to add in a couple of new regions. I've done this on the page that the master copy regions on and gone to do the next page and its still coming up NEW. Is this correct? Or should it pick up the new region from the original page?

Just wanted to check before I go any further.

Thanks
