You'll have to do the latter, i.e. call melodic from the command line.  
This is pretty straight-forward, i.e. list all the input files in an  
ascii text file (one input per line) and then pass this file to  
melodic as the input - select the other options as you please and  
that's it... as you say, it's relatively easy to do once you've had a  
good look at the log file from a completed run
