I have a workflow that works just fine when I output to my desktop using the usual output tool. It transforms data for a rollling 4 months each time, and then the data is saved into the file relating to the month:

Now I want to automate it fully, put it up on the server and have the output save the files into sharepoint, and I can't find a similar way to do this with the sharepoint output tool:

How can I do this?
