Is there a way to enable reflink on an existing XFS filesystem?

I currently have a 4TB RAID 1 setup on a small, personal Linux server, which is formatted as XFS in LVM. I am interested in enabling the reflink feature of XFS, but I did not do so when I first created the filesystem (I used the defaults). Is there a way that I can toggle the reflink feature on, without having to backup and re-create the filesystem? And if not, can I expect that feature to be implemented in the future?
