change airdroid desktop location to external sd cardquestion

Hello. I'm using airdroid 3.
with the osx applet i can easily upload files which is great. 
the thing is that I can't seem to find a way to change the location of android desktop in order for me to 
be able to upload files to the external sd card.

any ideas ?

using note 4 with android 5.0.1

Sorry, customizing the path of received files on phone is not supported now. And managing files in external SD card on Android 4.4+ with AirDroid is not supported due to some resctrictions. Sorry about that..
