Simlink and FLT Plan Compatible issues

Hello, so I use MSFS and when I fly VFR I use an app called FLT Plan Go and when I fly IFR I use Navigraph charts. And FLT Plan uses Port 1500. So it is impossible to use both, since I am both VFR and IFR pilot. Is there anyway I can change SimLink’s port cause I’m guessing it uses Port 1500. Cause when I reinstall FLT Plan it says Port 1500 is blocked and vice versa. I cant find a way to change the port in FLT Plan. Is there a way I can change SimLink’s port or a way so I can use both?
