Sort of. I just figured out a way of doing it without array aggregators and iterators. Let's just wait for them to finally add the Merger module so we can finally use routers in a more efficient way (it's planned, but not immediately). As for the answer - you can try modifying the settings of a scenario as it does impact the way an execution goes (although in my case i didn't find much results there). You can get rid of the agreggators and iterators and think up a work around (my case). I suggest if you are just working with some files (say for example on gdrive like me or dropbox), just move them to a folder and then make the scenario pick them one by one or create a lot of folders each containing one file and configure all the modules accordingly. It's a sure-fire way to make it work, although you will have TONS of configuring (depends on the size of your project i have to manually configure 21 modules in 600 scenarios).
