Set path for SASnRDisplay

Is it possible to tell sasnrdisplay where to find the .r-files? I have them in a seperate folder from my LaTeX-document, and I was wondering if there is a command like graphicspath{{"figure path"}} for figures or input{"settings path"} for settings, so I don’t need to feed the inputRcode command with the entire directory of the R-file.
I have tried looking in the documentation, but haven’t found anything there, so it might not exist. However I hope it is just me who is blind.
