TC & Brake Bias Screen for Dash

Hi,

I am trying to add a feature to my own dashboards where the Brake Bias or Traction Control flashes up on the screen for a short time when the setting is changed. I have seen it done on some demo dashboards and I have also seen it used on the F1 cars so i thought it would be a great feature for my dash. 

I have created a separate screen / dashboard for each of hte setting and it is reporting the correct info, i just need it to jump to the screen for a second when the setting is changed.

Can anyone help me out as to how you get the relevant screen to flash up as above.

Thanks for you help.
