Creating a segment will work if there is a clear pattern/similarities you see across the different data set you have collected (e.g. similarities in the page URL).
Moving forward, do consider populating a dimension (eVar or prop) that you can use to segment data for multiple pages (if this is a recurring use case) Like for example, you have numerous landing pages, product pages, and blog pages, I will populate some sort of a page category prop and fill in that value with the appropriate page category and then just do segmentation in Workspace to see aggregated data for the desired group of pages
The company I work for already does this, and depending on how organized you are, you can do it how either @Andrey_Osadchuk or @mikeetiuPH suggested. I can already tell you I am using a segment at the HIT level that gets everything that I need because the pages all start with a base-level name. If you're already using page naming conventions that work in your favor to use either of these approaches, you should be in good shape! Otherwise, you may have a little pre-work ahead of you.
