Launching EAs automatically vs manually

 
I want to launch/run 40 times the same EA (same code) to different (40 charts/symbols).
Is there a way to automatize this process (or run them all at once), or would I have to launch one after another, manually?
I really looked for an answer but didn't find it.
Finally, is there any inconvenient in doing what I am intending to do?
 
Maybe you can use templates and profiles to make things easier.
