Set an attribute as automatic default selection?

The version is Easy Populate 1.2.5.5.csv.2

Would the reason that EP4 didn't work is that it wasn't configured in some way for this file layout?

If by "not working" was meant that the desired file/filetype was attempted and all of the included data was not incorporated, then yes it would be because EP4 is by default only setup to handle certain options. Like all things Zen it can be customized, but is beyond the out of box default. It could be made possible.

It definitely helps to understand in future posts what "does not wor" means.
