Update to Yealink phone to display DND status of another extension?

Hello,

I wanted to follow-up on this forum and see if there is a firmware version available on the Yealink phones to allow BLF keys to indicate if another extension has "DND" enabled or if this is still in the works?  We have had several of our clients ask about this feature the past couple years and I wanted to see if this feature is still being pursued for Yealink phones?

Thank you!
