Hey Rumbledesign,
all pages of “Portfolio” layout in Ikebana are designed to display all portfolio items, thus only creating one more page would not help here; you can try using the portfolio tags as differentiators, and using the tag archive page URL for the second page; here’s an example tag page from the theme demo. By design, it can be reached by clicking on the “Services” icon menu item when not from the main portfolio page; you can use the direct URLs of such pages in menus etc to create links to “alternative” portfolio pages.
Sincerely,
Andrii / Satori Studio
