Question about ENS subdomains

I didn't find a ENS subreddit, so I hope it's fine asking here:

Etherscan.io shows ENS names instead of the normal public addresses now, but does that work for subdomains too?

I set 4 up and if I type them into Metamask they resolve to the right addresses, but etherscan.io still shows the normal 0x... Addresses instead of the subdomain names

So my question is, does etherscan.io not support subdomains, or do I still need to set something up?
