Rota clashes

We have different leaders rota-ing their teams on the app. Many people serve in multiple teams. Would it be possible for clashes to be highlighted on the scheduling matrix please? Maybe a change in text colour when someone's name is duplicated at a service.

I realise there is the option to check the calendar icon by each name within each specific service but with Sunday teams of 15-20, this isn't practical. The beauty of the scheduling matrix is to be able to schedule months ahead so having the 'clash' highlighted here would be beneficial.

Hoping you can help.
