Portfolio Grid Exclude Current Project

I am using the portfolio grid at the bottom of my portfolio item post to show the next few projects. It works great, except that I want to exclude the currently viewed project. It would work like this: open project 1, scroll to bottom of post, where projects 2, 3, and 4 are showing in the portfolio grid. However, the way it works now, project 1 is also showing in the portfolio grid at the bottom, which is unnecessary, since the user is already on that project post. Is there a way to make it automatically not show the project post that is currently being viewed in the grid? (Site is not live yet, so can’t send a link.)
