Setting download folder for Roon Arc on Astell & Kern SP3000 to external storage

I took the plunge on getting an Astell & Kern SP3000 once I heard that I could run Roon Arc on it. Now having received it and installed the Roon Arc app it appears that I can only use the internal storage on the SP3000 for downloads, when I was hoping to use the external storage (or ideally use both internal and external storage). Is this possible?



It is not currently but there are feature requests in asking for it.
