Yes, you can.

You are welcome to provide patches for the FAQs, etc.

Y can create N config files with the same content, but different batch-name,
if all the conf files are residing in the same directory

You are mixing up two different concepts.
If you have a batch and you are willing to spread it through N CPUs,
use -t N or -t N*2

yet another option is to run independently two parallel loads.

Since each load is writing log files be careful about not giving the same
names.

Sorry, but since you are not posting the PRF,
cannot help you any more.
