Adding Page Numbers and Systems

I'm new to Notion and just started a template with piano, bass and drums. I noticed that the blank measures just stopped at measure number 32. Is there a simple way to add additional systems (piano, bass & drums) and page numbers to my piece?
Currently, I'm copying a blank system measure and then doing an "insert paste" into order to add additional system measures to my piece - but there's got to be a better way to do this. I didn't see anything in the manual.
Thanks for your help.
