Easier way to publish a block on multiple pages?

Hi All,
We are working on a new site which is content heavy (over 120 pages) and this need to be publish into both our Staging and Prod URL, I just wanted to know if there an easier way to push all those pages live in one hit rather than going in one by one and pushing it live one page at a time? 

any help would be appreciated
