Add an option to pad auto-completed brackets with spaces

I like the auto-completion that is available in the QtCreator editor. However, it would be nice to have an option to pad auto-completed brackets with spaces. For example, I like to format my parenthesis like so:

// Function declaration inside of a class header file
void someFunction( int arg0, int arg1, int arg2, int arg3 );

However, when I go to write the implementation of this function in a .cpp source file, the auto-completion will fill in my list of arguments without the padding:

void someFunction(int arg0, int arg1, int arg2, int arg3)

It would be lovely to specify some default behavior for auto-completion within brackets.
