Applying heading style to multiple pages at once

[jane.bugai]

Hi All,



I was wondering if there is a way to apply heading style to multiple pages at once? I have a pretty long document and Word automatically defaults text to Normal Style. I would like to apply Heading 1 style to a specific section on a page. I also would like to repeat that for all pages in my document (100+). Is there a way to automate this function in Word or I have to manually apply the heading style to each page? Thank you all.
