You have to use MIK to analyse Camelot notation because MIK own the copyright to it so this is why pioneer, traktor etc cannot use it.
As I said, my nexus display Camelot notation on the display just like you are asking for and just like that video. It is perfectly possible for you to achieve it without any workaround. I'm not sure what you're doing wrong... Maybe start a new thread and I'll try and help you resolve it.
Also, you do realise that your 'drifting' loop issue is 100% down to you not fixing your beat grids? A wrongly set grid throws the quantising off.
