Cannot add KODI shortcut to home screen on Oct 2015 edition

Morning peeps.

So I bought myself a fire TV about a month ago, got it all set-up and love it. My ex-wife got her jealous on and ordered the new 4K version.

For whatever reason I cannot for the life of me get KODI to show up on recent.

I've done the Llama trick of changing the icon which works, but setting up an event that replaces Ikona TV with KODI fails miserably.
Have they added extra security to prevent this? Is there another way around using ES File Explorer, or another none-root hack that'll get this bad boy working?

Any help would be appreciated.

Thanks
