As RPI uses CSS profile, does RPI use IDOC to collect the supporting material?
I google their website and can’t find any description on how to submit the supporting material.
found it now. RPI does not use IDOC

On your application status page, they do have an upload materials button, but the option to classify it in the drop down menu only says “resume” for me. I just emailed my supporting financial documents directly to the financial office and you could probably do the same.
