Centering camera accross all meshes

I’m using an orthographic camera and have a single mesh right now using extrude geometry. The mesh starts drawing from the bottom-left corner, which I chose because it’ll be easier when I add more meshes later on, likely to the right side of my primary mesh.

However, this setup is causing an issue with positioning the camera. Is there a way to center my camera (x, y) across all the meshes? Thanks!
