Solidworks 2025 macro → setting option file to the template option file

Hi everyone,

i'm registered in many 3D cad forum. In the past year i did not find a single person who actually helped me out.

My problem is the following: i don't know how to write solidworks macro, but i need one that help me set mass in kg (with just one number after period) and set the file name with just the file name (i don't want to see (default)>) like below picture

Now i have setted template properly (with visualization file name just file name, and mass in kg with jus one number after period), but now all the old files (parts and assemblies) has the old setting like in the picture.

Does anyone have the macro i need? Or does anyone know where i can find the macro i need?

Thank whoever reply
