suggestion, just create a file and make it executable that includes
all your options
echo  sudo dd if=CentOS-6.10-x86_64-LiveDVD.iso of=/dev/sdc bs=4096
conv=fsync> $HOME/bin/ddforCent
put $HOME/bin in your $PATH
you could make several versions, with differing options
ddforSomesituation, ddforforsomeothersitutation etc


The last thing the world needs is another conf file, with its documentation
