Can i use the same MATLAB function in Simulink multiple times?

In Simulink I have a MATLAB function defined which I need at multiple calculation steps so I just copied the entire MATLAB function block.

Can I define the function in a separate .m-file so that if I update the function, every instance of it automatically uses the updated version? If so, how can I implement this?

I would assume so. Just create that function and save it in your MATLAB path and then call it in your MATLAB Function block. You may also consider using the "Fcn" block or "Interpreted MATLAB Function" block.
