Not as a SSRS datasource, just store physical files (.csv's or .xlsx's) on the SSRS Report Server in addition to the .rdl reports. When I manually upload a file to the Report Server the online storage address is like:

http://servername/Reports/Pages/Resource.aspx?ItemPath=/Foldername/filename.csv

Is it possible to connect to this online folder from SSIS and store data flow results there?
