[Word] Two Different Page Numberings

I’m doing some coursework here at school (so only have word to use) and I’m wondering if anyone can help my page numbering.

I’ve got seperate sections of the c/w in seperate documents, each with their own page numbering, e.g. (3/11) but I wanted to also have a count of ther total pages in the whole project, so starting from an arbitary number. I can’t see a way to do BOTH of these at the same time.

Any ideas?
