BB10 - Spotify - download files both on internal memory & external micro-sd card?

[taiarth]

I am using Z30 using OS 10.3.2.2474.

I downloaded Spotify from Amazon, have a Premium account and able to download music for off-line listening. However, instead of just downloading the files to the external micro SD card, it is also saving files to the internal memory as well.

When I go to "Storage" within spotify it shows files are download to :

/mnt/sdcard/external_sd &
/mnt/sdcard

and there is no way I can select one or another.

Any help of how to put the download exclusively to the external card is very much appreciated.
