Radio Altimeter on PFD and emergency situation

Hi,

can anyone please tell me how I can display the radio altimeter height on the PFD? On the PMDG 737 NGXu it is not displayed by default. Is that a company specific display option? Is there an option somewhere to activate it?

I think it is pretty useful during takeoff when you need to perform actions at certain heights AGL.
Then you dont need to do some math to reckon out the AGL with the baro displayed height.

Eg. on engine failure after V1 you normally need to climb to 400 feet AGL before you activate the heading mode for the FD. With only the baro height being displayed on a 350 feet above ground airport you need to reckon 400+350=750 feet to know when to activate heading mode. That is a little disturbing when the pilot is in an emergency situation.
Or am I understanding something wrong here?

Thanks!
