Modify existing build system in sublime text 3

I currently use the following build system in ST3 for compiling .cpp codes

{
    "cmd": ["mingw32-g++.exe", "-c", "$file", "-o", "${file_path}/${file_base_name}.o", "&&",
"mingw32-g++.exe", "-o", "${file_path}/${file_base_name}.exe", "${file_path}/${file_base_name}.o", "&&",
"start","${file_path}/${file_base_name}.exe"],
    "file_regex": "^(..[^:]*):([0-9]+):?([0-9]+)?:? (.*)$",
    "working_dir": "${file_path}",
    "selector": "source.c++,source.cpp",
    "shell": true
}

The problem I face is that, I need to type the inputs into the cmd one by one, which is time consuming.

Is there a possibility to somehow tweak the above build system so that I can perform the below action?

On cmd.
