Allow multiple commands in same execution

[germancasares]

Hi!

First of all, thank you for maintaining the fork!

I have a use case where I want to do something like:

A:/some/folder to B:/some/folder B:/another/folder to C:/some/different/name B:/foo/folder to C:/bar/ B:/foo/random to C:/john/ etc...

Like running multiple copy/sync commands. How could I pass an array of SRC/DEST instead of just 1 combination?
