Backup from Android don't keep folders

[Pixel60]

Hi,
 
I have installed the app on my Android and I am trying to make a full backup of all the multimedia files, the problem is that I have a lot of folders/albums full of photos and videos, which when doing the backup are all mixed in the same destination folder.
 
Is there no way to backup the same folders structure on the NAS?
 
I have a ReadyNas 102 with firmware 6.7.5 and an android mobile with the official app ReadyCLOUD 1.2.11
 
Thanks to all for the help!

Hello Pixel60,

We only support backup specified source folder's media file to the only one specified destination folder on nas without folder structure with mobile app now.

Best Regards.
