Precise heading readout in HUD?

[Gearbox]

Is there a way to get a numeric readout of your heading in the HUD instead of just the tape? I dug around in the IFCC menu and figured out how to turn the alt and speed readings into tapes, but not how to change the heading :(

You could put the CDU page up on one of the MFCDs and display the heading data from a CDU page?
