Contact Sensor alert - Is it customizable?

Greetings,Unfortunately i have been unable to get an answer to my question about the sensor alert.Hopefully i will find it here :slight_smile: I am planning to purchase the security package, including 3 contact sensors; 2 for the main/garden door, and 1 for my 3 year old child - bedroomdoor.My son is now slowly roaming around at night when he wakes up and i would like to be alerted if he opens his door. My question is; is it possible to receive an alert to my phone only for this sensor when he opens the door, without crazy alarms going off... so just phone only, preferably a sound of my choosing ? (like the standard alarm clock sound on my iPhone). The other sensors should have their standard intruder-alert sounds... no need to change that along with what i choose for the bedroom door.Is this possible with this Ring security system?
