Is it possible rename "Blogs" into "Sites" without altering code

I am using Framemarket theme and all the user sites are displayed as “Blogs”. We only use this site as marketplace so each user can have their own store, it makes sense to name their stores as “Stores” or “Sites” rather than “Blogs”.

Is there a fix to rename them all at once throughout the site into “Sites” or “Stores” instead of “Blogs” ?
