Hi @travis k

Yes it was introduced in UNA 13.  

UNA 13 is still in under development stage (Beta 4) and not completely ready for live or production sites. Some users are already running it on their live sites as it's quite stable and rich in new features, but i would advise you to test it first (of course on your dev site).

To see Beta releases in your Studio > Dashboard and update your UNA system, you will need to switch to Beta upgrade channel in Studio > Developer > Update channel.
