Ransomware and Onedrive - is there a solution ?

I use Onedrive that's linked to my Office 365 account, and it now seems to work quite well. The new client has made a considerable difference.

However, before I move everything across to OneDrive, I thought that I would check to see that I would be able to restore multiple files to a previous version, just as if I was hit my some Ransomware. It appears that OneDrive will only allow me to go back one version a single file at a time. This is very poor, and will prevent me from moving to OneDrive.

Am I missing something, or is this really the case ? Surely there must be some way of restoring multiple files back one version ? I find it hard to believe that Microsoft haven't thought about this.
