I believed what is being asked is a way to separate the portfolios. For instance, I have a page I want to display members, on another, I would like to display board members. In your portfolio builder, there isn’t a way to identify which portfolio would go in which category, members or board members.
When you create a simple post, you can choose which category to put the post in. I believe there is a short code to place the posts of one category exist so you could literally have all the post of one category show on a page.
