Users currently using Alteryx as a service on workbench have no means to export the output files directly to their workspace. Instead, they have to download the file to their local machine and then upload it back to workbench via file upload. This is discouraging them from adopting the former and they rather prefer to share the output using Google Drive where it isn't getting cataloged.
This is out of date now; we have the new Alteryx macros that can push to the Workbench WASB containers. We just need to advertise them more - once we are sure they work properly 100% of the time (ahem)
