If no and the script is simply too large, you can try using bluetooth mode + intiface. But usually scripts are large because there are excessive points, in which case it won’t feel right via Bluetooth. You may want to open up the script in OFS and reduce the number of points. You can do this by using the simplify function, or selecting all mid points and delete them.
