Auto Backup SD drive to MBWEII (White Lights) using WD Anywhere Backup

Using the backup software (WD Anywhere Backup) I can select any file on my local (C:) drive to automatically backup.

BUT

I store all of my personal files on an SD card that sits in my laptop (I can then swap between my home and work laptops and just swap over the SD card)

BUT

I can’t see how to automatcially backup the files I have on my SD (E:\drive) card to the MBWEII NAS Drive

Is this possible ?

Thanks,
