Windows Phone 8.1: OneDrive auto upload question.

[SRLumia620]

I created a new folder using the "Files" app on WIndows Phone 8.1 in the pictures folder, and moved some pictures into that folder again using the fantastic "Files" app. And rightfully so, this folder appears as a separate album in the Pictures hub as I intended. But I noticed that OneDrive does not automatically backup this folder into the cloud, unlike the Camera Roll, Screenshots and Saved Pictures albums. Is there a way to enable automatic backups for this album created by me?

Thanks in advance!
