Is it possible on the Lockdown screen for it to behave like any Android/iPhone device does when there is a text message you have not read or a phone call you have missed and shows the number over the SMS/Phone icon?

I have the Lockdown pointing to the default Android dialer (com.android.dialer) and using the default icon but when a device misses a call the only indication is the small phone icon in the top taskbar.

Interested if there is a way around this no matter how creative.
