Templates in the Restance Theme

Good day! Have created a real estate website using the Restance theme. However, we have encountered an issue with the templates in the theme – we can link each of the templates available in the theme to only one blog post with a property. And, ideally, we need 1 template for all the 20-30 pages with properties that we plan to have on the site. A template in which we could change photos in the Gallery and texts in Home Advantages/Features. I.e. Gutenverse/Restance has a template to blog-post ratio = one-to-one, not one-to-many. And we need 1 template for many blogposts. Can this be done? Would appreciate your insights!
